Louie Gohmert, who refused to wear a mask, tests positive for coronavirus

But footage from before the hearing shows Gohmert and Barr walking together in close contact, with neither wearing a mask.

Justice Department spokeswoman Kerri Kupec said Barr will be tested for coronavirus on Wednesday.

At one point in Tuesday's hearing, Chairman Jerry Nadler (D-N.Y.) chastised several Republicans for taking off their masks, though Gohmert was not among those he scolded.

"I would remind Mr. Jordan, Mr. Biggs and Mr. Johnson to stop violating the rules of the committee,” Nadler said, referring to Jim Jordan (R-Ohio), Arizona Rep. Andy Biggs and Louisiana Rep. Mike Johnson, three GOP lawmakers. “To stop violating the safety of the members of the committee. To stop holding themselves out as not caring by refusing to wear their masks.”

“Is it permissible to drink a sip of coffee?” one of the members asked.

“It is not permissible,” replied Nadler.

In a tweet, Nadler wrote, "I want to wish ⁦@replouiegohmert⁩ a full & speedy recovery. When individuals refuse to take the necessary precautions it puts everyone at risk. I’ve regularly instructed all Members to wear their masks and hope this is a lesson by all my colleagues."

House Majority Leader Steny Hoyer ripped Gohmert and some of his GOP colleagues for frequently not wearing masks in the Capitol.

“Too many Republicans have continued to act extraordinarily irresponsibly, including Louie Gohmert. Louie Gohmert ought to quarantine himself right now,” Hoyer told reporters.

Hoyer added that requiring lawmakers to be regularly tested for the virus should be discussed anew on Capitol Hill.

Connie Hair, Gohmert's chief of staff, declined comment. But after this article was published, Gohmert told his aides in person that he had been infected.
