During an interview that aired on Sunday, the former Vice President stood by his decision not to testify before the House committee about the deliberations at the White House.

During an interview on the CBS program "Face the Nation," Vice President Mike Pence told host Margaret Brennan that he had concerns about the makeup of the January 6 panel and that Congress had no right to hear his testimony.

I was in the Congress for over a decade. I don't think it's appropriate for one party to appoint every member of a committee in Congress. He said that he didn't stand in the way of senior members of his team testifying and cooperating with the committee.

"Congress doesn't have the right to my testimony," he said. The constitution of the United States gives us separation of powers. It would be a terrible precedent for the Congress to summon a Vice President of the United States to give a speech about deliberations that took place at the White House.

The former vice president said that he was closing the door on the appearance.

The partisan nature of the January 6 committee has been a disappointment to him. There was an opportunity to examine every aspect of what happened on January 6, and to do so more in the spirit of the 9/11 Commission.

Pelosi created a congressional committee after Senate Republicans blocked a bill establishing an independent, bipartisan commission. Jim Jordan of Ohio and Jim Banks of Indiana were removed from the committee after Pelosi rejected them.

When asked if the GOP would be open to self-reflection about January 6, he stated that his feelings were based on the separation of powers.

The fate of the committee structure and decisions that would be made would be left to other people. I think it's important that we uphold the separation of powers in the Constitution of the United States and that's where we'll be.

In his new book, "So Help Me God," which was released last week, he writes about his family, faith, and his time as vice president under Donald Trump.

Trump launched his campaign last week.

He has floated a presidential run of his own but hasn't made a decision.
