Four of the Republicans who called for the punishment of Greene also objected to the Electoral College count on January 6.
Three of the Republicans–Giminez, Kim, Malliotakis–joined the House on January 3, 2021. I guess they got to know Greene during orientation and didn’t like what they saw and heard.
