On Friday (Jan. 29), Democratic Rep. Cori Bush of Missouri made the announcement that she would be changing her office at the United States Capitol after getting into a heated exchange with GOP Rep. Marjorie Taylor Greene of Georgia earlier this month.

Apparently, the conflict stemmed from the fact that Taylor wasn’t wearing a mask on her face while in one of the government building’s hallways. The fallout was immediately taken very seriously by Speaker Nancy Pelosi, who quickly ordered the location change for Bush to feel more safe.

“A maskless Marjorie Taylor Greene & her staff berated me in a hallway. She targeted me & others on social media. I’m moving my office away from hers for my team’s safety” Bush tweeted Friday.

A spokesperson for Green named Nick Dyer also commented on the incident by claiming that it was Bush who, in fact, initiated the argument. “Rep. Bush is actually the instigator and it’s on tape. We’ll be releasing the video shortly,” he said. The statement was then followed by a video clip that was posted, which showed Green speaking on her cell phone before viewers can hear someone asking her to put her mask on.

“Bush did not dispute the fact that she confronted Greene, starting the altercation. Bush repeatedly asked Greene to put on a mask, to which Greene and Greene’s staff criticized Bush on an unrelated issue,” CNN reports.

The news outlet continues: “In her tweet, Bush also joined a growing list of her Democratic colleagues calling on Greene to be expelled from Congress after a fountain of highly inflammatory comments Greene has previously made have come to light.”

Democratic Rep. Ilhan Omar of Minnesota has also defended Bush during this ordeal by tweeting that Greene’s actions were a “red flag” and Bush “moving her office doesn’t mitigate the threat.”
