Everyone in his administration, from Pence all the way to the halls of the U.S. Congress! Especially the Republican "leadership", like Ryan, Scalise, McCarthy in the House and McConnell and his minions in the Senate!

...more politically savvy traitors like Pence, or if not Pence then Ryan.

They are all knew what was going on, have seen all the same evidence and have done nothing. Therefore they are equally traitorous, but they put a happier, all american face to their treason.
