(CNN) -- Artificially-generated faces of people who don't exist are being used to front fake Facebook accounts in an attempt to trick users and game the company's systems, the social media network said Friday. Experts who reviewed the accounts say it is the first time they have seen fake images like this being used at scale as part of a single social media campaign.The accounts, which were removed by Facebook on Friday, were part of a network that generally posted in support of President Trump and against the Chinese government, experts who reviewed the accounts said. Many of the accounts promoted links to a Facebook page and website called "The BL." Facebook said the accounts were tied to the US-based Epoch Media Group, which owns The Epoch Times newspaper, a paper tied to the Falun Gong movement that is similarly pro-Trump.The publisher of the Epoch Times denied that Epoch and The BL were linked in emails to the fact-checking organization Snopes earlier this year.In a statement released after this story initially published on Friday, Epoch Times publisher Stephen Gregory said, "The Epoch Times and The BL media companies are unaffiliated. The BL was founded by a former employee, and employs some of our former employees. However, that some of our former employees work for BL is not evidence of any connection between the two organizations."The BL is a publication of Epoch Times Vietnam. As can be seen in archived pages of The Epoch Times website, Epoch Times Vietnam was no longer listed as part of Epoch Media Group in October 2018."In response, a Facebook spokesperson told CNN Business that executives at The BL were active administrators on Epoch Media Group Pages as recently as Friday morning.The dystopian revelation of the use of artificially-generated images in this way points to an increasingly complicated online information landscape as America enters a presidential election year. Silicon Valley and the US intelligence community are still struggling with the fallout from widespread online interference in the 2016 presidential election.The Facebook accounts used profile pictures that appeared to show real people smiling and looking directly into a camera. But the people do not and have never existed, according to Facebook and other researchers. The images were created using artificial intelligence technology. The same basic methods are used to produce deepfake videos — fake videos that the US intelligence community has warned could be used as part of a foreign disinformation campaign targeting Americans.Other fake accounts that were part of the same network used stolen pictures of real people, according to the social media investigations company Graphika and the thinktank the Atlantic Council. Facebook provided information to Graphika and the Atlantic Council for analysis in advance of Friday's announcement.The accounts were used to run dozens of pro-Trump Facebook groups with names like "America Needs President Trump," and "WE STAND WITH TRUMP & PENCE!," according to Graphika and the Atlantic Council.The fact-checking organizations Snopes and Lead Stories had reported in recent weeks and months about the use of artificial images on Facebook that were part of this network of accounts. Snopes published a story last week criticizing Facebook's apparent inaction on the issue. Facebook said Friday it had "benefited from open source reporting" in the takedown but said that its own systems that monitor for coordinated and inauthentic behavior had proactively identified many of the accounts.In a joint report on their findings, Graphika and the Atlantic Council outlined how they were able to determine which of the profile photos had been generated using artificial intelligence. "This technology is rapidly evolving toward generating more believable pictures, but a few indicators still give these profile pictures away," they said.Images generated using artificial intelligence, specifically by a machine-learning method known as a GAN, or generative adversarial network, are "notorious for struggling with features that should be symmetrical on the human face, such as glasses or earrings, and with background details. Profile pictures from the network showed telltales of all three."GANs consist of two neural networks — which are algorithms modeled on the neurons in a brain — facing off against each other to produce real-looking images. One of the neural networks generates images (of, say, a woman's face), while the other tries to determine whether that image is a fake or a real face.While experts were able to spot these telltale signs on close inspection, it is likely the regular Facebook user would not.Over the past year, a number of websites have emerged online that create fake faces using artificial intelligence.Researchers from Graphika and the Atlantic Council could not conclusively determine if the people behind the fake accounts had used artificial pictures from these public sites or had generated their own.In their report released Friday, Graphika and the Atlantic Council said, "The ease with which the operation managed to generate so many synthetic pictures, in order to give its fake accounts (mostly) convincing faces, is a concern. Further research is needed to find ways to identify AI-generated profile pictures reliably and at scale, so that platforms and researchers can automate their detection."Connection to Epoch Media GroupIn all, Facebook said Friday, it had removed a network of 610 Facebook accounts, 89 pages, 90 groups, and 72 Instagram accounts. About 55 million accounts followed one or more of the pages, and the vast majority of followers were outside the United States, Facebook said. Facebook did not say if all of all these followers were real — some of them may themselves have been fake accounts.The network of pages removed on Friday had spent almost million on Facebook ads, according to Facebook.Facebook's investigation primarily focused on "The BL" (The Beauty of Life) — a set of Facebook pages and a website that says its goal is to "present to the world the most beautiful aspects of life."The pages often shared pro-Trump and anti-China content.On its website, The BL outlined the dangers of "inaccurate and degenerate information" that it said "can be easily channeled toward vulnerable or uninformed people."The purpose of the fake accounts, including those using fake faces, appears to have been to promote links to The BL's website and Facebook pages, Ben Nimmo, director of investigations at Graphika told CNN Business on Friday.Facebook said the fake accounts were tied to the US-based Epoch Media Group and "individuals in Vietnam working on its behalf." The company did not outline precisely how it made the connection, but in recent years Facebook has hired a team of investigators to find fake accounts on the platform.The Epoch Times newspaper is part of the Epoch Media Group. The newspaper has almost 6 million followers on Facebook. Nathaniel Gleicher, Facebook's head of security policy, told CNN Business Thursday that Facebook was not suspending the newspaper's account but investigations into Epoch's behavior on Facebook were ongoing.Snopes reported earlier this month that the publisher of the Epoch Times denied that The BL and Epoch were linked.In August, Facebook banned ads from The Epoch Times after an NBC News investigation detailed how the newspaper was secretly running pro-Trump Facebook ads under alternate accounts. The Epoch Times' publisher said in a statement to NBC News, "The Epoch Times advertisements are print-subscription advertisements describing our paper's reporting — a popular practice of many publishers — and every one of these ads was approved by Facebook before publishing."A Facebook spokesperson said the company shared its findings with Twitter and Google, which owns YouTube.A Twitter spokesperson confirmed in a statement Friday, "today we identified and suspended approximately 700 accounts originating from Vietnam for violating our rules around platform manipulation — specifically fake accounts and spam.""Investigations are still ongoing, but our initial findings have not identified links between these accounts and state-sponsored actors," the spokesperson added.Google did not immediately respond to CNN Business' request for comment. 8341

SAN MARCOS, Calif. (KGTV) - A San Marcos family is dealing with an unbearable loss. The Houghton family was involved in a horrific crash that killed their 13-year-old son, Bryce, Saturday night on the 405 in Orange County. The family of five was headed to San Luis Obispo to visit relatives, according to Michael Houghton. Their 17-year-old daughter was driving, when their van began to slow down. Michael says it seemed like it was running out of gas. It stopped in the HOV lane. Michael, his wife, and three kids decided to stay in the van buckled up and call for help. While they waited for 911 and a tow truck, CHP says a pickup truck slammed into the van. Another vehicle hit the pickup truck after the initial crash. The CHP arrested the driver of the pickup truck on suspicion of DUI. Officers said the driver of the pickup had major injuries. Four people in the third vehicle received minor injuries. Michael described his youngest son as a jovial person who loved to make people smile. “Short in stature but big in personality,” Michael said. “One of the things he loved the most was to make people happy.” The Houghton’s other two children, 15-year-old Mason, and 17-year-old Carissa, received minor injuries, though Mason will be on crutches, according to his dad. Michael’s wife, Gael, needed surgery. Michael received injuries to the back of his head, and injuries to his eye that had previously undergone a procedure. The family was very involved with Anthem Church in Vista, as well as Bread of Life Rescue Mission in Oceanside. The Houghtons had organized an event for the homeless on the Saturday before the crash. Bryce was a student at San Elijo Middle School. Mason and Carissa go to San Marcos High School. There is a GoFundMe page started for the family. 1799

With the Syrian Civil War entering its ninth year this month, the Trump administration is proposing to zero out all new US funding for stabilization efforts in the country.This move comes as the administration is pressing allies to step up their commitment to the ongoing crisis both militarily and financially and as the US is pulling most of its troops out of the country.Members of Congress from both parties, some of whom are re-introducing legislation this week that would prevent taxpayer dollars from going to reconstruction in any areas in Syria controlled by Assad, are calling this a mistake that strengthens the Assad regime and hurts efforts to defeat ISIS."It is a dangerous decision," Democratic Rep. Brendan Boyle of Pennsylvania, one of the sponsors of the No Assistance for Assad Act, said. "It ends up essentially signaling a green light to this mass murderer that he and his awful allies, like the Iranian regime, will be able to just do carte blanche whatever they want."Boyle points out the plan, which is contained in the administration's State Department budget proposal, would hurt efforts to secure the release of American citizens being detained in Syria.As of last summer, the US had spent a total of million in northeast Syria on counter-ISIS stabilization efforts, according to the former anti-ISIS envoy, Brett McGurk. That money had been spent on projects including efforts to get clean water running, supporting schools so that students can return, clearing extensive rubble and demining areas so they are livable for returning Syrians.The State Department did not reply when asked for an update on those figures.Despite this budget proposal, the State Department says that the US remains committed to peace and stability in Syria. They also claimed that there is some money available from previous years in the Relief and Recovery Fund that could possibly be used in Syria, though they did not detail how much."US policy priorities in Syria remain unchanged," said a State Department spokesperson. "We are committed to the enduring defeat of ISIS and al Qaeda, a political solution to the Syrian conflict in line with United Nations Security Council Resolution (UNSCR) 2254, and the removal of all Iranian-led forces in Syria."Critics say plan undermines fight against ISISBut members of Congress and experts argue the plan undermines efforts to defeat ISIS."I consider the war on terror to be generational and it is not gonna be a fight that is just only done by military. There is a military component, but it is also giving people hope and opportunity. And, you know, spending a few hundred million dollars to help stabilize a region to help give people some hope is far cheaper than, you know, releasing missiles, which we are going to have to do, and bombs, which we are going to have to do," Republican Rep. Adam Kinzinger of Illinois said, adding "it is a bad move."More than 5 million in stabilization funds was raised last year by the 15 members of the coalition to defeat ISIS, including 0 million from Saudi Arabia and million from the United Arab Emirates. That is enough to ensure the continuation of ongoing stabilization projects, for now. That money was raised after the US pressed countries to step up their contributions.Critics suggest out that the proposal to eliminate the US contribution will anger allies who had been asked to share the burden.There have been signals that the Trump administration was headed in this direction of curtailing US spending in Syria. Last summer the State Department announced that it would not be using 0 million that had been appropriated for stabilization efforts in the country. The decision came just weeks before the end of the fiscal year, which prevented Congress from taking meaningful action to reverse the decision.It has never been a secret that President Donald Trump wanted to exit Syria -- both militarily and financially. Throughout his time on the campaign trail he promised he would withdraw US troops from the country.Yet lawmakers and allies were stunned and outraged in December of last year when Trump suddenly declared that the US troops would be exiting the country within a matter of months, shortly after a phone call with Turkish President Erdogan.At the time, South Carolina Republican Sen.

 President Donald Trump's legal team is preparing answers to written questions provided by special counsel Robert Mueller, according to sources familiar with the matter.The move represents a major development after months of negotiations and signals that the Mueller investigation could be entering a final phase with regard to the President.The questions are focused on matters related to the investigation of possible collusion between Trump associates and Russians seeking to meddle in the 2016 election, the sources said. Trump's lawyers are preparing written responses, in part relying on documents previously provided to the special counsel, the sources said."We are in continuing discussions with the special counsel and we do not comment on those discussions," said Trump attorney Jay Sekulow.There may be more rounds of questions after the first answers are returned. The special counsel had insisted that there be a chance for follow-up questions as well. But after a prolonged back-and-forth over months, the two sides agreed to start with a first round of questions.Additionally, the two sides have still not come to an agreement on whether the President will be interviewed in person by investigators who are also probing whether Trump obstructed justice by firing FBI Director James Comey.Asked on Thursday about answering Mueller's questions, Trump again signaled his willingness to sit down for an interview with Mueller or provide written responses -- the option much preferred by his attorneys."It seems ridiculous that I'd have to do it when everybody says there's no collusion, but I'll do what is necessary to get it over with," Trump said in a phone interview on Fox News. Despite Trump's insistence to the contrary, the possibility of collusion remains an open question in the ongoing investigation led by Mueller, who has not tipped his hand one way or the other.Negotiations for Trump's testimony lasted for the better part of a year. The two sides nearly reached a deal in January for Trump to be questioned at the presidential retreat in rural Maryland, Camp David, only for talks to break down at the last minute. What followed was a series of letters and meetings -- some hostile -- in which Trump's lawyers raised objections and sought to limit any potential testimony.For months, Mueller told Trump's lawyers that he needed to hear from the President to determine his intent on key events in the obstruction inquiry. During one tense session in March, Mueller raised the possibility of getting a subpoena to compel the President's testimony.Trump's lead attorney John Dowd resigned later that month. According to a recent book published by journalist Bob Woodward, Dowd quit because he believed Trump would never heed his advice to avoid an interview at all costs. Trump once publicly said he was "100%" willing to go under oath to answer questions about his decision to fire Comey, who led the original Russia investigation before Mueller was appointed.The President eventually hired Rudy Giuliani to join his legal team, and the former New York mayor quickly took to the airwaves to defend Trump and attack Mueller. As Giuliani made the rounds on TV newscasts -- blasting the investigation as illegitimate -- Trump's other lawyers, Jane and Marty Raskin, carefully worked behind the scenes with Mueller's team to narrow the topics that Trump could be asked about. 3444
