The House select committee investigating the Jan. 6 insurrection at the US Capitol just wrapped up its seventh public hearing. 

The committee focused on the role of extremist groups and how the violent mob came together. The hearing explored the Trump administration's connections to these groups, such as the Proud Boys and the Oath Keepers, ahead of the riot.

In closing remarks, Cheney revealed Trump himself attempted to call a witness to the select committee's investigation, and the panel turned over the information to the Department of Justice.

"After our last hearing, President Trump tried to call a witness in our investigation, a witness you have not yet seen in these hearings," Cheney said. "That person declined to answer or respond to President Trump's call and instead alerted their lawyer to the call. Their lawyer alerted us and this committee has supplied that information to the Department of Justice."

She continued: "Let me say one more time; We will take any effort to influence testimony very seriously."
