(CNSNews.com) - Members of the House Judiciary Committee are holding mock hearings today, Chairman Jerrold Nadler (D-N.Y.) said, in preparation for tomorrow's testimony from former Special Counsel Robert Mueller.
But in his interview with CNN's "New Day," Nadler would not say who, if anyone, is playing the role of Mueller as part of today's dress rehearsals.
Democrats have a lot riding on Wednesday's back-to-back congressional hearings, at which they hope to "break the lies" put out by President Donald Trump and Attorney General William Barr.
But no matter what emerges from Mueller's five hours of testimony, there is more to come, Nadler said.
As I said, our goal is to break the lies of the president and the attorney general in saying that the report found no collusion, found that there was no collusion, that there was no obstruction and exonerated the president," Nadler told CNN. "It did not exonerate the president. The report is chock-full of very damning information against the president.
Again, as I said, it found ten instances of the president obstructing justice. It found instances of the president instructing people to lie to investigators and to lie to the American people. And the American people need to hear this from Mueller.
And then after that, we need to get some of the witnesses cited by Mueller before the committee. Now, the administration has done what no administration has ever done before. They've stonewalled all subpoenas, they've said no one will testify. We will break that and we will hear from people like Don McGahn, etc. and they will testify. And people will know what the report found, will know the facts and then can make judgments.
Nadler noted that most people have not read the 448-page report, and he and other Democrats are trying to give them the movie version of what's in it.
But regardless of whether tomorrow's hearings sway public opinion, there is more persuasion still to come.
Host Alisyn Camerota told Nadler, "It's not going to be over tomorrow for all of you."
"Oh, no, it is certainly not going to be over," Nadler agreed.
"We're going to court in the next few days, as I said before, to try to force people like Don McGahn and Hope Hicks and various other people who are fact witnesses who who testified to the Mueller committee, to come before the committee and testify in open hearings as to what they saw, so that the conclusions of the Mueller investigation can be laid open, not only the conclusions but that people can see the testimony of these people and form judgments."
Nadler said Committee Democrats assume that Mueller will do what he said -- "he'll stay more or less within the bounds of the report."
But Nadler said he and other Democrats "will be referring to specific pages and specific sections in the report and asking him to comment on it."
Nadler gave an example: "Well, paragraph two on page whatever says the following, is that correct? Did you find that? Does this describe obstruction of justice?"
Nadler said there are three tests when considering impeachment:
"One, do you conclude there's real proof the president has committed impeachable offenses," he said.
"Number two, are these impeachable offenses serious offenses. And number three, is there enough evidence public, so that impeaching the president would not tear the country apart? And I think it's very important that the people understand the evidence that there is so that they and therefore the committee and the Congress can make that judgement."
Mueller's investigation ended without indicting the president. "I think it's very clear he (Mueller) left it to Congress, and we have to exercise our powers," Nadler said.
