Sen. Thom Tillis (R-N.C.) took a shot at Rep. Marjorie Taylor Greene (R-Ga.) Tuesday, saying she is “dragging our brand down."

“She is a horrible leader,” Tillis said of Greene, according to audio played on CNN's “Erin Burnett OutFront." “She is dragging our brand down. She — not the Democrats — are the biggest risk to us getting back to a majority.”

He added that the Georgia Republican is “uninformed” and “a total waste of time,” per the clip, highlighted my Mediaite.

His criticism comes as Greene has been in the spotlight over her motion to vacate threat against Speaker Mike Johnson (R-La.) and her outspoken opposition to providing more aid to Ukraine in its war against Russia.

A package of foreign aid bills — including Ukraine and Israel aid — easily passed the House over the weekend, and after debate, advanced through the Senate earlier Tuesday. President Biden is expected to sign the bills Wednesday.

Following the House vote, Greene lashed out at Johnson and her GOP colleagues who helped push the additional aid through. She specifically called out the Speaker as a "traitor," in a post on social media platform X.

“Johnson once again passed a bill with the help of Democrats while the majority of the Republican majority voted against it,” Greene wrote. “Not only is Mike Johnson a traitor to our conference, he’s a traitor to our country.”

Tillis wasn't the first Republican to call out Greene. Rep. Marc Molinaro (R-N.Y.) said in an interview last week that the Georgia lawmaker's political “theater” must “come to an end,” likely referring to her threat to oust Johnson

Last Thursday, in an interview on former White House aide Steve Bannon's "War Room" podcast, Greene said she did not care if the “Speaker’s office becomes a revolving door."

“If that’s exactly what needs to happen, then let it be," she added. "But the days are over of the old Republican Party that wants to fund foreign wars and murder people in foreign lands, while they stab the American people in their face.”

Despite the threat, Greene has not given a timeline for when she will bring her motion to vacate resolution to the floor for a vote.

The Hill has reached out to Greene's office for comment.
