A Republican from Georgia traded insults with a colleague who sided with his political opponents instead of supporting his fellow party member.

Rep. Marjorie Taylor Greene (R-Ga.), criticized Senate Minority Leader Mitch McConnell (R-Ky.) for showing a lack of loyalty and giving in to the Democratic Party.

“The real cancer for the Republican Party is weak Republicans who only know how to lose gracefully,” she said on Twitter.

The congresswoman believes McConnell’s decision to support a House Democrat bid to relieve her of all committee duties will not bring unity to Congress.

“This is why we are losing our country,” Greene said.

The remarks came after the McConnell took the unusual step of condemning Greene’s loyalty to former President Donald Trump and the policies he championed during the previous Trump administration.

“Loony lies and conspiracy theories are cancer for the Republican Party and our country,” McConnell said, according to Reuters.

He then claimed social media posts that Greene allegedly liked back when she was a private citizen proved she was too extreme to represent people living in the Peach State’s 14th congressional district.

“[We are talking about] somebody who has suggested that perhaps no airplane hit the Pentagon on 9/11, that horrifying school shootings were pre-staged, and that the Clintons crashed John F. Kennedy Jr.’s airplane is not living in reality,” he said.

Reps. Debbie Wasserman Schultz (D-Fla.), Ted Deutch (D-Fla.), and Jahana Hayes (D-Conn.) jointly introduced a resolution to remove Greene from her seats on the House education and budget committees.

The political stunt came after House Democrats found no constitutional way to silence the Republican.

‘We cannot stop her from speaking’

“We cannot stop her from speaking,” Wasserman Schultz said, according to Reuters. “What we can do though, is essentially render her nearly powerless—that is what the intent of this resolution is.”

The trio also gave the GOP an ultimatum to distance itself from the Greene or face a House Rules Committee hearing on Feb. 3.

“It is my hope and expectation that Republicans will do the right thing and hold Rep. Greene accountable, and we will not need to consider this resolution,” House Majority Leader Steny Hoyer said. “[However,] we are prepared to do so if necessary.”

Greene believes the Democrats will keep abusing the House Rules Committee if they are allowed to remove her.

“If Democrats remove me from my committees, I can assure them that the precedent they are setting will be used extensively against members on their side once we regain the majority after the 2022 elections,” she said on Twitter. “We will regain the majority. Make no mistake about that.”
