"They said it's a slam dunk. Now the House managers, they got their impeachment, they have their trial, everyone is sworn in, dressed up and ready to go," Hannity, a staunch supporter of the president, said in a monologue.

"Present your slam-dunk case," Hannity continued as the trial extended into his 9 p.m. time slot. "They didn't call the witnesses that they now are demanding to be called. They have the sole power to impeach, [but] they think the U.S. Senate now should spend months doing their constitutional job."

“The beady-eyed lunatic you’ve been watching on your screen all day is, perhaps, my view the worst liar in all of politics," the host added in reference to Schiff. "He said he had significant evidence, for three years, he told us — is Trump-Russia collusion. That was a lie.”

Hannity also said that any Republicans who allow House Democrats "special treatment they don't deserve" will "be adding legitimacy to this unconstitutional corruption."

"If you give the House Democrats — if your representatives allow the House Democrats the special treatment they don't deserve, that's unconstitutional. You are literally a part of what is a charade that will live in perpetuity, that is ripping this country apart. You, your representatives, your senators will be adding legitimacy to this unconstitutional corruption."

Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE (R-Ky.) was able to push through a rules resolution strictly along party lines in a 53-47 vote just before 2 a.m. on Wednesday morning. The resolution included a rejection of additional witnesses and documents at the outset of the proceeding as pushed for by Democrats.

At one point, things became so heated that Chief Justice John Roberts, who is presiding over the Senate trial, stepped in to warn House impeachment managers and Trump’s lawyers to watch their respective tones after attacks became personal in the arguments over procedure.

“It is appropriate at this point for me to admonish both the House managers and president’s counsel in equal terms to remember that they are addressing the world’s greatest deliberative body,” Roberts warned.

“One reason it has earned that title is because its members avoid speaking in a manner and using language that is not conducive to civil discourse,” the George W. Bush appointee added.
