House Majority Whip James Clyburn (D-SC) went on CNN on Sunday to demand that former President Donald Trump be forced to testify before the House Select Committee investigating the January 6 Capitol riot.

“The new chair of the January 6 committee, Bennie Thompson, did not rule out calling former President Trump to testify. Do you think that a full investigation requires hearing from him?” asked host Dana Bash, according to The Hill.

“Bennie Thompson is well experienced at the state and local levels before coming to Congress. He’s headed to Homeland Security Committee for a long time,” Clyburn replied. “I think he knows that we know what happened. We know where it happened. What we don’t know is why it happed and who made it happen? He intends to get to those last two questions and do so in a bipartisan way.”

“What do you think?” asked Bash. “Do you think former President Trump should testify?”

“Oh, if it comes to that, they should go where ever the facts lead. They may be able to get what they want and need without him testifying,” Clyburn replied. “I would not want to see a former president testifying in such a situation like this, but if that’s what it takes in order to get to the bottom of this because this is more than one person. In this country, we are celebrating today an independence. Since 1776 this country has been in pursuit of perfection. We need to keep that pursuit going. We can’t stop it. This is a great time for us to rededicate ourselves to what we all have been looking forward for a long time liberty and justice for all.”

Clyburn also gave his thoughts on the Democrats’ push to change the rules regarding the filibuster.

“We need to get rid of the filibuster for constitutional issues, just as we have done for budget issues,” he said, according to Politico.

Clyburn then said that the filibuster allows senators “to sit downtown in a spa somewhere, pick up a telephone and call in a filibuster and effectively stop constitutional rights.”

“[They] won’t even come to the floor to argue his or her position; that’s what is wrong with the filibuster,” he continued. “That’s what they’ve done to it.”
