WASHINGTON (AP) — The number of immigrants in the U.S. without legal status has declined to its lowest level in more than a decade, according to a new report released Tuesday.The nonpartisan Pew Research Center said 10.7 million immigrants lacked legal status in 2016, down from 11 million a year earlier and from a peak of 12.2 million in 2007 before the U.S. economy slumped.It is the lowest number since 2004, the report said.The decline stems largely from a drop in the number of Mexican immigrants living in the U.S. illegally to 5.5 million in 2016 from nearly 7 million in 2007. Some returned to their country to reunite with family, while others were deported.During the same period, the number of immigrants from Central America without legal status increased to nearly 1.9 million from 1.5 million.The report comes as the Trump administration has cracked down on immigration and bolstered security on the Southwest border, where thousands of Central American families have arrived to seek asylum.The report is based on U.S. Census Bureau data. It also noted an increase in the number of immigrants without legal status from India and Venezuela and a decrease in those from Brazil, Colombia, Ecuador, Korea and Peru.Overall, immigrants without legal status are less likely to be recent arrivals, said D'Vera Cohn, who co-authored the report.The report also notes that the number of legal immigrants grew to 34.4 million from 28.3 million over the nine-year period, and that more than half of the country's legal immigrants in 2016 were naturalized U.S. citizens. 1579

WASHINGTON (AP) — Twitter says it will crack down on accounts and content related to QAnon, the far-right U.S. conspiracy theory popular among supporters of President Donald Trump.The company said Wednesday it will ban accounts associated with QAnon content and block sharing of associated URLs."We will permanently suspend accounts Tweeting about these topics that we know are engaged in violations of our multi-account policy, coordinating abuse around individual victims, or are attempting to evade a previous suspension — something we’ve seen more of in recent weeks," said Twitter.Twitter also said it will stop highlighting and recommending tweets associated with QAnon.The company said it was taking action against online behavior that could lead to offline harm."These actions will be rolled out comprehensively this week," wrote Twitter. "We will continue to review this activity across our service and update our rules and enforcement approach again if necessary."The QAnon conspiracy theory is centered on the baseless belief that Trump is waging a secret campaign against enemies in the “deep state."Trump has retweeted QAnon-promoting accounts.Its followers flock to the president’s rallies wearing clothes and hats with QAnon symbols and slogans. 1268

WASHINGTON, D.C. – The United States has reached another grim milestone in the COVID-19 pandemic, surpassing 9 million coronavirus cases.That’s according to a tally by Johns Hopkins University, which also shows the U.S. is closing in on 230,000 deaths from COVID-19.America continues to lead the world in the total number of cases and deaths, with India and Brazil quickly catching up.The milestone comes as around most states across the U.S. report increases in infections. Data shows the seven-day rolling average for daily new coronavirus cases in the U.S. rose over the past two weeks from 52,350 to more than 74,180.This marks a return to infection levels not seen since the summer surge.This recent surge comes on the heels of the 2020 presidential election, where the pandemic is top of mind for most voters. However, the candidates are framing the COVID-19 crisis in different ways. President Donald Trump is claiming the U.S. rounding the curve and is promising to return to country to normal with a forthcoming vaccine.Meanwhile, former Vice President Joe Biden is zeroing in on how the Trump administration has handled the pandemic, claiming it was mismanaged and far too many people have died or gotten sick. 1228

WASHINGTON (AP) — The Pentagon plans to free up a big chunk of its military airwaves in the U.S. for high-speed internet service, part of a broader push to get ahead of China in the deployment of 5G wireless technology. The Trump administration announced Monday that it has identified radio spectrum used for radar defense systems that can be shared with commercial telecommunications providers without compromising national security. White House officials said that the Federal Communications Commission will be able to auction the 100 megahertz of “mid-band” spectrum beginning in December 2021 for use as soon as mid-2022. 633

WATCH THE LAUNCH:(KGTV and CNN) - Friday morning's launch of a SpaceX rocket from the Central California coast will be a notable one for Elon Musk's out-of-orbit efforts.A Falcon 9 rocket is scheduled to blast off from Vandenberg Air Force Base at 7:13 a.m. PT. The rocket will deliver a group of satellites for communications firm Iridium (IRDM).Shortly after launch, SpaceX is probably going to make another experimental attempt to guide the rocket's nose cone, also called a payload fairing, onto a passenger ship outfitted with a giant net.PHOTOS: SpaceX?rocket launch visible above San DiegoThe fairing rests on the very top part of the rocket, and it acts as a shield for satellites during launch. Once the rocket is in space, the fairing splits into two and falls away. Typically, it's left to plummet back to Earth where the ocean becomes its graveyard.But SpaceX wants to change that, mostly because the fairing on its Falcon 9 costs million.As Musk once put it, if "you had million in cash on a palette flying through the air, and it's going to smash into the ocean, would you try to recover it? Yes. Yes, you would."The company has quietly attempted to recapture the 43-foot-long fairing halves since at least March of 2017.At least twice, SpaceX has guided fairing halves to soft landings in the ocean, according to Musk's social media pages.But there's a problem."Once it gets into the water, it's quite damaging to the electronics and components inside the fairing," said Glenn Lightsey, a professor of aerospace engineering at Georgia Tech. "Most likely if it gets into the water, it's not usable."Enter, Mr. Steven.For Friday's launch a ship, named Mr. Steven, will head out to sea and attempt to catch half of the fairing with a giant net. 1810
