WATCH: Senator Ted Cruz slams Democrats for ‘political theater’ and refusals to address the nation’s real problems

"This is political theater because rather than address the real problems, the real challenges we have in this country. Rather than focus on getting kids back in school, and getting tens of millions of Americans back to work, the Democrats want a week of just political theater raging at Donald Trump."

Speaking to Sean Hannity on Tuesday night, Cruz said "I think today typifies what we're going to see this week, which it reminds me of Shakespeare. It's full of 'sound and fury signifying nothing.' We're going to see this week a whole lot of Democrats pounding the table, we're going to see a lot of moralizing. And a lot of really venting their hatred for Donald Trump.

"In case you haven't been paying attention the last four years, the Democrats really, really, really hate Donald Trump. And they're going to attack Donald Trump over and over and over again. They're going to bring in—the idea that they've got [Eric Swalwell (D-CA)] coming in.

"I do hope he gives some remarks on improving our relations with China, he has a novel approach to that," Cruz said, referring to Swalwell's involvement with a woman named Fang Fang, who worked both in his California office, as a spy for the Chinese Communist Party, and who had a sexual relationship with the representative who serves as an Impeachment Manager during this trial.

"But this is going to be just venting the id of the Democrats, and then it's gonna end in failure," Cruz said. "It is going to end with the president being acquitted. In order for the president to be convicted it takes 67 votes in the US Senate.

"That's not going to happen. It's not going to get 67 votes. It's not going to get close to 67 votes. Every one of the 100 senators knows that. Every one of the House Managers knows that," Cruz said.

During the first four hours of the impeachment hearing on Tuesday, Democrats recounted the personal ordeals they faced during the Capitol Hill riot on Jan. 6, detailing their own fears and emotional turmoil rather than present evidence that either Trump was responsible for the actions of those rioters.

The first day of the hearing was intended to determine whether proceeding with an impeachment trial for a president who is no longer president was constitutional. The vote to proceed, 56 to 44, broke down along party lines, with only six Republicans siding with Democrats on the issue of constitutionality.

Those six Republicans were Susan Collins of Maine, Bill Cassidy of Louisiana, Lisa Murkowski of Alaska, Sen. Mitt Romney of Utah, Sen. Ben Sasse of Nebraska, and Sen. Pat Toomey of Pennsylvania.
