House Democrats introduced a resolution Monday to remove Georgia Republican Marjorie Taylor Greene from her committee assignments over her history of violent threats and racist, anti-Muslim and anti-Semitic comments.

On Monday, Senate Republican leader Mitch McConnell did not mention Greene directly by name, but referred to her “loony lies and conspiracy theories” — describing them as a cancer for the Republican Party. McConnell told The Hill, “Somebody who’s suggested that perhaps no airplane hit the Pentagon on 9/11, that horrifying school shootings were pre-staged, and that the Clintons crashed JFK Jr.’s airplane is not living in reality.”
