Asha Rangappa, an analyst for CNN and a former special agent for the FBI, tweeted a thread on Tuesday in which she said, “We have a biological terrorist in the White House.” This follows President Donald Trump returning to the White House on Monday evening after treatment for the Coronavirus at a military hospital and the news that more senior White House and military officials testing positive for the virus.

In defending her claim, Rangappa cited a Justice Department memo stating back in March that the novel Coronavirus “appears to meet the statutory definition of a biological agent” and that those who engage in the “purposeful exposure and infections of others” could be charged for terrorism-related offenses.

While there are some allegations that he knew about his positive diagnosis significantly earlier than he had announced it on Thursday evening, there is no certifiable evidence that he knowingly exposed officials and staffers to the virus.

For her tweet, Rangappa has received heavy criticism on Twitter.

Mr. and Mrs. Trump both tested positive for COVID-19 on Thursday evening, alongside many political figures and staffers. The exact event where the President caught the virus remains uncertain.

However, the theory gaining the most traction supposes that the infection occurred at the Rose Garden ceremony where he announced Judge Amy Coney Barrett as his Supreme Court nominee on Saturday, September 26. Since many of those who were also infected attended the event, many place this as the “superspreader” event.

Since the end of last week, more and more White House officials have tested positive for COVID-19. On Monday, Press Secretary Kayleigh McEnany announced her positive diagnosis following a weekend where she engaged with numerous reporters. On Tuesday, most of the nation’s top military leaders said that, after reports of multiple infections, they would enter quarantine.

Sens. Mike Lee (R-Utah) and Thom Tillis (R-N.C.), both members of the Senate Judiciary Committee, which holds hearings on Supreme Court appointees, have also tested positive for the virus, alongside Republican National Committee Chair Ronna McDaniel.
