Yes, I posted a copy of the corresponding oath that was sworn to during the Clinton impeachment (in another thread). I also related that Lindsey Graham stated in an interview (I think it was on FOX) that he has no intention of being fair in the impeachment proceedings. And Moscow Mitch McConnell has gone public with his current collusion with the White House to determine how the impeachment proceedings should go in the Senate. So obviously, they could care less about another oath.
