WASHINGTON _ President Donald Trump's national security adviser has tested positive for COVID-19 days after attending a family function, White House officials said Monday.
Robert O'Brien, Trump's fourth national security adviser, is the highest-level U.S. government official known to have tested positive for the novel coronavirus since the pandemic began.
One of the president's top advisers with a corner office in the West Wing, the national security adviser typically comes in regular contact with the president. But since attending a family gathering roughly a week ago, O'Brien has worked away from the White House and has not had contact with either the president or Vice President Mike Pence, sources said.
