"He will be called to testify; he'll invoke executive privilege, perhaps," Dershowitz told Tuesday's "Spicer & Co.," stressing that the former president can invoke executive privilege. "Perhaps he'll want to testify. The American public does have a right to know what happened.
"The key is individual responsibility. This is something that happened collectively, but every individual person must be held accountable for what they did and didn't do — the president included."
Dershowitz warned to co-host Lyndsay Keith and guest host Seth Denson that Pelosi's seven-Democrat and two anti-Trump Republican committee will only give the "Democrat truth" and they will cover the storming of the Capitol with a large cover that runs the risk of tarnishing good people who did not do bad things.
"You can't judge this thing collectively, and so I think the focus has to be on a particular person," Dershowitz announced. "What did they do? And we have to know the facts."
For example, Dershowitz explained, he is representing a Washington student "who went into the Capitol not to obstruct justice, but simply to defend the senators who were calling for hearings" on charges of election fraud.
Dershowitz pointed to the Chicago Seven case in 1970 where all seven accused in a conspiracy to rebel over the Vietnam War were acquitted.
"The courts held that every individual was an individual and had to be treated as an individual under the First Amendment," Dershowitz stated.
Though Dershowitz continued, this is not a trial, yet partisanship and using a "terrible, tragic event" to get "partisan advantage."
"In Washington today, it's impossible to do anything without trying to get some partisan advantage, and that's why I think this hearing will fail," Dershowitz stated. "I think in the end we won't learn the truth. We will learn Democratic truths and we will learn Republican truths, but we won't learn the actual truth because no one is interested in the truth.
"Everybody is interested in advancing their partisan interests. Unfortunately, that is the case."
"The American people are entitled to know what actually happened, the actual truth. We're not going to learn it from partisan investigations."
Cheney, in her opening statement, likewise made clear the committee is open to subpoenaing the former president, White House aides, and members of Congress as they build a timeline of the day.
"We must also know what happened every minute of that day in the White House. Every phone call, every conversation, every meeting, leading up to, during, and after the attack. Honorable men and women have an obligation to step forward," she stated.
