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

President Donald Trump "believes he has the power to" fire special counsel Robert Mueller, White House press secretary Sarah Sanders said Tuesday."He certainly believes he has the power to do so," Sanders said when asked whether Trump believes he has that power.She did not suggest Trump would be moving to fire Mueller.Under the special counsel regulations, Mueller may be "disciplined or removed from office only by the personal action of the attorney general." Attorney General Jeff Sessions has recused himself from all matters related to the 2016 presidential campaign, so only Deputy Attorney General Rod Rosenstein has the power to fire Mueller.Trump does have the ability to fire Rosenstein, for no reason at all, as a member of the executive branch. 766

Potential accuracy issues with a widely used coronavirus test could lead to false results for patients, U.S. health officials warned.The Food and Drug Administration issued the alert Monday to doctors and laboratory technicians using Thermo Fisher’s TaqPath genetic test. Regulators said issues related to laboratory equipment and software used to run the test could lead to inaccuracies. The agency advised technicians to follow updated instructions and software developed by the company to ensure accurate results.The warning comes nearly a month after Connecticut public health officials first reported that at least 90 people had received false positive results for the coronavirus. Most of those receiving the false results were residents of nursing homes or assisted living facilities.A spokeswoman for Thermo Fisher said the company was working with FDA “to make sure that laboratory personnel understand the need for strict adherence to the instructions for use.” She added that company data shows most users “follow our workflow properly and obtain accurate results.”The FDA said one possible problem was related to the incorrect use of equipment that rapidly spins samples in preparation for processing. The agency’s letter tells lab workers to follow new instructions developed by the company for this step.A second issue relates to the software used on Thermo Fisher’s testing platform. FDA said labs must upgrade the software to a new version.Dr. Albert Ko of Yale’s School of Public Health said the potential accuracy problems have “pretty serious implications” given that Thermo Fisher’s test is used widely both in the U.S. and around the world to screen for coronavirus.The FDA statement did not provide any details on how many test results may have been affected by the problem.Lab tests are the backbone of U.S. screening for coronavirus, accounting for more than half of the roughly 750,000 tests developed daily. The tests look for traces of coronavirus’ genetic material in nasal swabs taken from patients.Thermo Fisher’s test was granted emergency use by the FDA in mid-March. The test runs on a large, automated machine used in hospital, government and commercial labs to look for diseases such as HIV, hepatitis and flu.The FDA has used its emergency powers to OK more than 200 tests for coronavirus since February. No test is perfect and all are expected to give at least a small percentage of false negatives and false positives.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

President Donald Trump is asking the Supreme Court to allow him to block critics from his personal Twitter account. The administration said in a high-court filing Thursday that Trump’s @realdonaldtrump account with more than 85 million followers is his personal property and blocking people from it is akin to elected officials who refuse to allow their opponents' yard signs on their front lawns. “President Trump’s ability to use the features of his personal Twitter account, including the blocking function, are independent of his presidential office,” acting Solicitor General Jeffrey Wall wrote in urging the justices to review the case.The federal appeals court in New York ruled last year that Trump uses the account to make daily pronouncements and observations that are overwhelmingly official in nature. It held that Trump violated the First Amendment whenever he blocked a critic to silence a viewpoint.A decision about whether even to hear the case is not likely before the November election. 1012
