Randomized coronavirus testing will become mandatory for staff of the Executive Office of the President as of today, a White House official tells CNN.
“As part of our ongoing efforts to protect the health and safety of the entire White House Complex, randomized testing of Executive Office of the President staff, which has been ongoing for several months, will become mandatory rather than voluntary," this official said.
Some background: President Trump's national security adviser, Robert O'Brien, tested positive for Covid-19 last week, according to an official familiar with what happened.
O'Brien's diagnosis marks the highest-ranking Trump administration official known to have tested positive. It's unclear when O'Brien last met with Trump. Their last public appearance together was over two weeks ago during a visit to US Southern Command in Miami on July 10.
