Each day for the past week, reporters have asked White House officials the same question: When did President Trump last test negative for the novel coronavirus? Each time, the White House dodged.

Deputy White House press secretary Brian Morgenstern’s appearance on MSNBC on Friday was no different.

“We don’t have that,” Morgenstern said, one of 10 different dodges to variations of the same question that he gave over five minutes. It was also the third time he had sidestepped that question over the past four days.

At least three other White House officials have dodged the same question for six straight days, examples of which you can watch in the video above. Trump’s last negative test is one of several pieces of incomplete or contradictory information about his coronavirus infection that the White House has refused to clarify. Health experts have said the negative test information is needed to know how long Trump may have been contagious and who might have to isolate after coming into contact with him.

On Saturday, White House physician Sean Conley declined to say when Trump last tested negative.

On Tuesday, Morgenstern said he did not know when Trump last tested negative.

And by Thursday, White House communications director Alyssa Farah told reporters, “I can’t reveal that at this time, the doctors would like to keep it private.”

Earlier this week, two officials familiar with the situation told The Washington Post that Trump had not been tested daily for the virus in recent months.

In the six days before he announced his positive test Trump traveled to six cities, including to Cleveland for the first presidential debate Sept. 29.

At least 34 White House staff members and other contacts have since tested positive for the virus, some of whom may have been infected at White House and Republican National Committee events late last month for Trump’s Supreme Court nominee Judge Amy Coney Barrett.

On Friday, the nation’s top infectious-disease expert, Anthony S. Fauci, called the Barrett ceremony a “superspreader event.”

“We had a superspreader event in the White House, and it was a situation where people were crowded together and were not wearing masks,” Fauci told CBS News. “So the data speak for themselves.”
