Look, this is easy: Rep. Marjorie Taylor Greene (R-GA) was out of line in a committee hearing Thursday night when insulting other members’ physical appearance and intelligence, and House Oversight Committee Chairman James Comer (R-KY) was derelict in failing to control his committee adequately.

No ifs, ands, or buts. Decorum matters. House rules matter. Greene violated both. And she is a habitual offender of proper decorum. House leadership now should retroactively “take down” from the record not just her original, insulting words but her subsequent slam at a colleague’s intelligence. Moreover, leaders should warn her that if she doesn’t start behaving better, she will lose committee assignments.
