The Jan. 6 select committee tasked with investigating the deadly attack at the Capitol is calling for a trio of House Republicans to cooperate voluntarily with its investigation, according to letters sent to the lawmakers on Monday.

The panel, probing the Capitol riots in which supporters of defeated President Donald Trump tried to overturn President Joe Biden's 2020 victory, wants cooperation from GOP Reps. Andy Biggs, Mo Brooks, and Ronny Jackson.

While it’s unclear whether the Trump-allied lawmakers will comply with the request, members of the panel are hoping they will meet with the committee as soon as next week after the House returns from its recess.

“The Select Committee has learned that several of our colleagues have information relevant to our investigation into the facts, circumstances, and causes of January 6th. As we work to provide answers to the American people about that day, we consider it a patriotic duty for all witnesses to cooperate,” Chairman Bennie Thompson (D-MS) and Vice Chairwoman Liz Cheney (R-WY) said in a statement.
