Incoming Rep. Marjorie Taylor Greene and another new Republican House member were involved in a dispute over coronavirus masks as the 117th Congress met for the first time on Sunday, journalist Jake Sherman reported.

Greene and the unidentified Republican appeared to tell floor staff they would not put on masks, Sherman reported.

The Republican and Democratic floor staff ended up in a “screaming match,” Sherman said.

Greene was quick to respond to the report.

“Speaker [Nancy] Pelosi changed the COVID rules because she is desperate to cling to the gavel. No one can attack me about masks, when Pelosi is sending Democrats to the floor with positive COVID tests to vote for her for Speaker,” Greene wrote on Twitter in an apparent reference to Rep. Gwen Moore, D-Wis., who will be allowed to vote on the floor after announcing Dec. 28 that she tested positive for coronavirus.
