You're correct. That was McCarthy's choice to make. The problem for Pelosi was she and the Jan 6 committee had already decided on the crimes and verdict--as any good show trial does--and needed Yes Men on the committee to make that happen.
The committee didn't investigate the Capitol riot. They made a show of investigating Trump so they could pronounce crimes against him, and proclaim him guilty.
As for Cheney, she voted 96 percent of the time with Republicans while she was anti-Trump. And, there was no "insurrection," so there.
That was a false post from beginning to end. Was it on Fox?
