Prenatal exposure to ambient air pollution was associated with an increased risk of autism spectrum disorder, a new study finds. Pregnant women in Vancouver who were exposed to the highest level of environmental nitric oxide, an airborne, traffic-related pollutant, were more likely to give birth to children later diagnosed with autism, the researchers say.Autism spectrum disorder, a developmental disability, is characterized by problems with communication and social interaction with accompanying repetitive behavior patterns.Lief Pagalan, lead author of the study and a member of the faculty of health sciences at Simon Fraser University, cautions that the study, published Monday in the medical journal JAMA Pediatrics, showed only an association between prenatal exposure to nitric oxide and autism rates. It did not prove that air pollution caused autism.Experts emphasize that the exact causes of autism remain unknown, and some say the researchers in this study did not analyze every potential risk factor.Still, the research "adds to the growing concern that there may be no safe levels of exposure to air pollution," Pagalan wrote in an email."Not only did we have access to rich data, enabling us to develop one of the largest studies to date, but we were also able to conduct this study in a city with relatively lower levels of air pollution," he said. 1375

President Donald Trump on multiple occasions raised with Deputy Attorney General Rod Rosenstein and Matt Whitaker, who was then-chief of staff to Jeff Sessions, whether the Justice Department was progressing in investigating Hillary Clinton, according to a source familiar with the matter.The President also wanted his previous White House counsel, Don McGahn, to ask the Justice Department to prosecute Clinton on numerous occasions, but McGahn rebuffed doing that, the source said.Anticipating the question about Clinton would be raised, Whitaker came prepared to answer with what Justice was doing on Clinton-related matters, including the Clinton Foundation and Uranium One investigations, the source said. The source added that Whitaker was trying to appease the President, but did not seem to cross any line.The New York Times first reported on Trump's requests to McGahn to prosecute Clinton, as well as former FBI Director James Comey.The Justice Department did not immediately respond to CNN's requests for comment.In March, then-Attorney General Sessions revealed that Utah's top federal prosecutor, John Huber, was looking into allegations that the FBI abused its powers in surveilling a former Trump campaign adviser, and claims that more should have been done to investigate Clinton's ties to a Russian nuclear energy agency, which have not been proven.And in January, CNN reported that the US attorney and FBI in Arkansas were investigating allegations of corruption related to the Clinton Foundation. The FBI and federal prosecutors are looking into whether donors to the foundation were improperly promised policy favors or special access to Clinton while she was secretary of state in exchange for donations to the charity's coffers, as well as whether tax-exempt funds were misused, the official said. A spokesman for Clinton dismissed the allegations as unfounded.William Burck, a lawyer for McGahn, issued a statement following the Times report that said the President hadn't ordered prosecutions of Clinton or Comey."Mr. McGahn will not comment on his legal advice to the president. Like any client, the president is entitled to confidentiality. Mr. McGahn would point out, though, that the president never, to his knowledge, ordered that anyone prosecute Hillary Clinton or James Comey," Burck said.The White House did not immediately respond to CNN's requests for comment.This is a breaking story and will be updated.The-CNN-Wire 2460

President Donald Trump returned to the Oval Office on Wednesday for the first time in five days following his three-day stay in Walter Reed Medical Center. Trump was released from the hospital on Monday.On Wednesday, Trump released a video statement on Twitter to reassure Americans he is feeling well. Despite complications from the coronavirus late last week, which included a high fever and low oxygen levels, the president said that his coronavirus infection was a “blessing from God.”While the president may still be contagious from the virus, there are questions on when the president first tested positive for the virus, and when his last negative test was. Knowing when the president first contracted the virus is important as those with the virus are still considered contagious 10 days after the onset of the virus, according to the CDC.“I wasn’t feeling so hot,” Trump said. “And within a very short period of time, they gave me Regneron… It was like unbelievable.”The Regeneron treatment is formally known as "REGN-COV2," and is an experimental drug that has only been trialed on 275 patients before the president’s infection. The treatment is a combination of two monoclonal and was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19, the company said. REGN-COV2 is still early in its trial process to test for efficacy and side effects. “I want everyone to get the same treatment as your president, because I feel great,” Trump said. “I feel like perfect. I think this was a blessing from God that I got it.”Trump went on to blame China for the spread of the virus, and said he wanted to make treatments free to Americans. 1682

President Donald Trump issued a statement declaring victory in Tuesday's presidential election, adding that he believes that the election is being stolen.There is no evidence at this time of any widespread election or voting fraud.When Trump spoke from the White House early Wednesday morning, opponent Joe Biden held a narrow 225-214 Electoral College lead. "I want to thank the American people for their tremendous support. Millions and millions of people voted for us today. And a very sad group of people is trying to disenfranchise that group of people. And we won't stand for it. We won't stand for it," Trump said.A number of battleground states remain uncalled, including Pennsylvania, Wisconsin and Michigan, North Carolina. With an influx of mail-in voting, states are needing more time than usual to count ballots. Officials in Pennsylvania have said that the vote count there could take days. The winner of Pennsylvania could be what decides the winner of the election.“We are up BIG, but they are trying to STEAL the Election. We will never let them do it. Votes cannot be cast after the Polls are closed!” Trump tweeted.Immediately after the message was sent, Twitter flagged the tweet for misinformation.In response, Biden campaign manager Jen O'Malley Dillon called Trump's comments "outrageous, unprecedented and incorrect.""It was outrageous because it is a naked effort to take away the democratic rights of American citizens," she wrote. 1465

President Donald Trump on Sunday warned of a "big price" after reports of a chemical weapons attack in Syria almost a year to the day since the US struck a Syrian air field."Many dead, including women and children, in mindless CHEMICAL attack in Syria," Trump tweeted. "Area of atrocity is in lockdown and encircled by Syrian Army, making it completely inaccessible to outside world. President Putin, Russia and Iran are responsible for backing Animal Assad. Big price..."He continued, "....to pay. Open area immediately for medical help and verification. Another humanitarian disaster for no reason whatsoever. SICK!"Syrian activist groups on Saturday said toxic gas inside barrel bombs dropped from helicopters over a rebel-held city in Syria killed dozens of civilians and wounded scores more. Syrian state news said an "official source" denied the allegations. 872
