President Joe Biden called a Fox News reporter’s question “stupid” as members of the press were ushered out of a White House auditorium following a meeting with the President’s Council of Advisors on Science and Technology, according to a pool report.

“What a stupid question,” Biden said Thursday after Fox News White House correspondent Jacqui Heinrich asked “why are you waiting on Putin to make the first move, sir?,” the pool report said.

The Biden administration spent much of Thursday walking back multiple statements the president made during Wednesday’s press conference, including his stance on a potential Russian invasion of Ukraine.
