The House select committee investigating the Jan. 6 Capitol Riot said that former President Donald Trump had been informed “to do something” on the day to stop the violence.

According to vice-chair of the committee Rep. Liz Cheney, R-Wyo., former first daughter Ivanka Trump asked her father to intervene at least two times.

"We know [Donald Trump's] daughter -- we have firsthand testimony that his daughter Ivanka went in at least twice to ask him to 'please stop this violence,'" Cheney told ABC News.

Ivanka Trump, 40, served as a senior advisor in the Trump administration. She also served as director of the Office of Economic Initiatives and Entrepreneurship. As president, Donald Trump often spoke highly of Ivanka and once stated that she would make an "incredible" U.S. ambassador to the U.N.

On Sunday, House committee chair Rep. Bennie Thompson, D-Miss., told CNN on “State of the Union” that, "We have significant testimony that leads us to believe that the White House had been told to do something. We want to verify all of it so that when we produce our report and when we have the hearings, the public will have an opportunity to see for themselves."

"The only thing I can say, it's highly unusual for anyone in charge of anything to watch what's going on and do nothing," Thompson said.

The purpose of the committee is to "investigate and report upon the facts, circumstances, and causes relating to the January 6, 2021, domestic terrorist attack."

After more than 300 witness interviews, the committee is expected to soon go public with the findings.
