"I'm the first one to confess that - the spirit that I brought to Washington, that I wanted to see instituted, where we weren't constantly - in - in a political slugfest but were focused more on problem solving that, you know, I haven't fully accomplished that. Haven't even come close in some cases. And, you know, if you ask me what's my biggest disappointment, is that we haven't changed the tone in Washington as much as I would have liked."
