If these 3 whiney-a$$ed, a$$holes don't like the way the GOP leadership runs the majority they should switch their affiliation to demonRATs and try to get elected as what they are...demonRATs.
Witness and judiciary intimidation aren't allowed in legal proceedings. Don't see how this is any different. There needs to be permanent oversight of Congressional ethics. I'd prefer to see it come from outside of Congress, however (foxes don't make the best guardians of chicken-coops). A citizen's task-force selected in the same manner as a trial-jury would be the best answer, IMHO.
