He told Hannity: “No American, including Donald Trump, should be accused of misdeeds without confronting their accuser, which is the whistleblower, and no American should be denied the ability to tell their side of the story by calling witnesses to explain their defense. That’s being denied the President of the United States.”

“So why am I not going to watch this tomorrow? Because I think it is a threat to the presidency. I don’t want to legitimize it, it’s un-American, it denies the basics of due process.”

He said that he wanted his colleagues in the Senate to “step up and say what is going on in the house is unfair, un-American, we’re not going to bless it. I would like Republicans to say, ‘this is a bunch of garbage.'”
