As someone who once criticized President Barack Obama for offering public timelines on American military engagement overseas, US President Donald Trump may have backed himself into a corner following his own promise to respond, and respond harshly, to the deadly chemical attacks in Syria.Last week he declared he wanted to withdraw US troops from Syria as soon as possible. But the suspected use of chemical weapons in Syria over the weekend may force him to reevaluate the US mission in that country.Vowing on Monday to come to a decision "over the next 24 to 48 hours" on how to make Syria pay a "big price," Trump's White House now appears to be scrambling to match its policy to his words.Trump tweeted Wednesday that missiles "are coming" in response to a threat from Russia to shoot down missiles coming into Syria.  836

Authorities are investigating interference with police radio communications, websites and networks used by law enforcement and other officials during recent U.S. protests over the death of George Floyd in Minneapolis.Although the efforts to disrupt police radios and take down websites in Minnesota, Illinois and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that law enforcement should be ready for such tactics as protests continue.Authorities have not yet identified anyone responsible or provided details about how the disruptions were carried out. But officials were particularly concerned by interruptions to police radio frequencies during the last weekend of May as dispatchers tried to direct responses to large protests and unrest that overshadowed peaceful demonstrations.During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the U.S. Department of Homeland Security.Dallas police did not respond to questions about the incident.The assessment, which was obtained by The Associated Press, attributes the Dallas disruption to “unknown actors” and does not say how they accessed the radio frequency. It warned that attacks of various types would likely persist.“Short-term disruptive cyber activities related to protests probably will continue — various actors could be carrying out these operations — with the potential to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.The assessment noted similar problems with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 followed by reports of arson, theft and vandalism. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”Police around the country have encrypted their radio communications, often arguing that it’s a way to protect officers and block criminals from listening in on widely available phone apps that broadcast police radio channels. But media outlets and local hobbyists have been frustrated by the changes, which also prevent them from reporting on issues pertaining to public safety.The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.Law enforcement agencies have been targeted by online pranksters or hackers in recent years, including by some who claimed to be motivated by on-the-ground protests against police tactics. For example, the hacking collective Anonymous claimed responsibility for the defacement of local police departments’ websites in 2012 as protesters clashed with officers during the Occupy Wall Street movement.Individuals who self-identified as being part of the collective also claimed to have accessed dispatch tapes and other Ferguson Police Department records in 2014 after a white police officer shot and killed Michael Brown, an 18-year-old black man.Like other government entities, law enforcement agencies in recent years have been frequently targeted by ransomware attacks, in which a perpetrator virtually locks up a victim’s computer files or system and demands payment to release them.The prevalence of cyberattacks — which can cause physical damage or far-reaching disruption — and less severe online trickery, such as stealing passwords, has given law enforcement agencies more experience at fending off efforts to take down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to keep up, said Morgan Wright, chief security officer for the cybersecurity company SentinelOne.“The biggest concern they have right now is the safety of their communities, the safety of their officers,” Wright said of how law enforcement agencies view cyberthreats amid large demonstrations and unrest. “But if you look at what underpins everything we use to communicate, collaborate and operate, it’s all technology.”As large protests gathered steam after the May 25 death of Floyd, a handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov. Tim Walz said state networks had been targeted. He described the activity as a “a very sophisticated denial of service attack.”But experts said the strategy of bombarding a website with traffic is common and doesn’t always take a high level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.But the efforts got a lot of attention, partly due to unverified online claims that Anonymous was responsible after years of infrequent activity. The decentralized group largely went quiet in 2015 but is still known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.Twitter users also made unverified claims that Anonymous was behind recent intermittent outages on the city government’s website in the Texas capital of Austin. Their posts indicated that the disruption was retribution for police officers shooting a 20-year-old black man in the head with a bean bag during a May 31 protest outside of police headquarters.The injured protester, identified by family as Justin Howell, remained hospitalized Wednesday in critical condition.The city’s IT department was looking into the site’s issues, but a spokesman said Monday that he couldn’t provide any information about the cause. He said the website was still experiencing a high volume of traffic.“You should have expected us,” an account purporting to be Anonymous’ posted on Twitter. It also warned that “new targets are coming soon.”The collective’s approach — anyone can act in its name — makes it difficult to verify the recent claims of responsibility. But Twitter accounts long affiliated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal who has studied the Anonymous movement for years.People with more advanced and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that type of activity will resume, she added.“There’s a lot of things going on in the background, people are chatting,” Coleman said. “Whether or not it materializes is another question. But certainly people are kind of aroused and talking and connecting.”___Foody reported from Chicago.

Attorney General Jeff Sessions' private attorney said Wednesday that the attorney general is not under investigation by special counsel Robert Mueller's office for perjury related to statements made at his confirmation hearing.In response to?an ABC News report saying that now-dismissed FBI official Andrew McCabe had authorized an investigation into whether Sessions lied to Congress about his contacts with a top Russian diplomat, attorney Chuck Cooper said Mueller's office has informed him that Sessions is not being investigated over his testimony."The special counsel's office has informed me that after interviewing the Attorney General and conducting additional investigation, the Attorney General is not under investigation for false statements or perjury in his confirmation hearing testimony and related written submissions to Congress," Cooper said in a statement to CNN.The special counsel's office declined to comment.A source close to Sessions said he was not aware of any investigation into possible perjury when McCabe was fired last week.CNN reported in January that Sessions was questioned for several hours by Mueller's team as part of the investigation into Russian election meddling and any possible collusion with President Donald Trump's team. A source familiar with the matter told CNN that Cooper was unaware of any possible perjury investigation related to Sessions before it was revealed by the ABC report.Sessions has repeatedly said that he didn't mislead senators or lie under oath.Vermont Democratic Sen. Patrick Leahy and then-Minnesota Democratic Sen. Al Franken wrote to then-FBI Director James Comey last March asking the FBI to investigate Sessions' testimony. The ABC report said McCabe opened the probe after the letter.A representative for McCabe declined to comment on the ABC story, which said top lawmakers of both parties were informed about the probe in a private briefing from McCabe in May, where Deputy Attorney General Rod Rosenstein also attended.A spokesman for Leahy said Wednesday that the senator was "not otherwise made aware of an investigation" into Sessions for perjury and that the FBI had declined to "confirm or deny the existence of an investigation" as of May 2017.Sessions confirmed last year that he met with Sergey Kislyak, the former Russian ambassador to the US, on two occasions: once on the sidelines of the Republican National Convention in July 2016, and then in his office in September 2016, when Sessions was a member of the Senate Armed Services committee.Sessions did not, however, mention either meeting during his confirmation hearing last January -- a fateful choice that has cast a long shadow over his tenure at the Justice Department.The critical exchange took place in January 2017, when Franken read from a CNN story about the dossier on Trump and Russia, and asked Sessions: "If there was any evidence that anyone affiliated with the Trump campaign communicated with the Russian government in the course of this (2016) campaign, what would you do?"Sessions responded: "I'm not aware of any of those activities. I have been called a surrogate at a time or two in that campaign and I did not have communications with the Russians."He further replied, "no," when asked whether he had been "in contact with anyone connected to any part of the Russian government about the 2016 election, either before or after Election Day" in his Senate questionnaire.For over a year, the attorney general has faced scrutiny from lawmakers on Capitol Hill about those portions of his testimony.After his confirmation hearing, The Washington Post reported on Sessions' undisclosed meetings with Kislyak, prompting members of Congress to call for Sessions to resign or step aside from overseeing the FBI's investigation into potential coordination between Russian officials and the Trump campaign.Kislyak, a career diplomat, was considered to be one of Russia's top spies and spy-recruiters in Washington, according to current and former senior US government officials -- though Russian officials dispute that characterization. Ultimately, Sessions recused himself from all investigations related to the 2016 campaign and Mueller was appointed special counsel.Sessions has steadfastly maintained that he was honest in his testimony."It simply did not occur to me to go further than the context of the question and list any conversations I may have had with Russians in routine situation, as a I had with numerous other foreign officials," Sessions said at a Senate Intelligence Committee hearing last June."I have never met with or had any conversations with any Russians or any foreign officials concerning any type of interference with any campaign or election," he added.Sessions later said he did not recall a third alleged private meeting with Kislyak on April 27, 2016, at the Mayflower Hotel in Washington, where then-candidate Trump delivered his first major foreign policy speech.Finally, in November, Sessions testified that he vaguely remembered a March 2016 meeting with Trump campaign aide George Papadopoulos, but said he had "no clear recollection of the details" of what was said at the time. Papadopoulos pleaded guilty last fall to making false statements to investigators about his interactions with foreign officials close to the Russian government."After reading (Papadopoulos' account), and to the best of my recollection, I believe that I wanted to make clear to him that he was not authorized to represent the campaign with the Russian government, or any other foreign government, for that matter," Sessions told House members. "But I did not recall this event ... and would gladly have reported it had I remembered it, because I pushed back against his suggestion." 5791

Authorities have identified a Facebook post believed to have been made by the gunman who killed 12 people at a bar in California, a law enforcement official said.Ian Long, 28, burst into the Borderline Bar & Grill in Thousand Oaks and opened fire with a Glock .45-caliber handgun as patrons line-danced late Wednesday night.Long is believed to have posted the social media message around the time of the attack, according to the official, who is familiar with the investigation.In it, the writer says: "I hope people call me insane ... (laughing emojis).. wouldn't that just be a big ball of irony? Yeah ... I'm insane, but the only thing you people do after these shootings is 'hopes and prayers'.. or 'keep you in my thoughts'... every time... and wonder why these keep happening. " 796
