The White House says it's vital to get a complete understanding of the Jan. 6 Capitol riot even as the House committee investigating the incident struggles to get former President Donald Trump's aides to comply.

"As the president has said before, Jan. 6 was one of the darkest moments in our country's history, and it's vital that we have a full accounting of what happened to ensure it never occurs again," said White House spokeswoman Karine Jean-Pierre on Wednesday.

MARK MEADOWS GAVE 'REAL-TIME COMMUNICATIONS' DURING JAN. 6 RIOT TO HOUSE INVESTIGATORS

Jean-Pierre's comments come after former Trump chief of staff Mark Meadows was held in criminal contempt of Congress for refusing to cooperate with the investigation into the Capitol riot.

Chairman Bennie Thompson wrote Wednesday that "the Select Committee is left with no choice but to advance contempt proceedings and recommend that the body in which Mr. Meadows once served refer him for criminal prosecution."

Jean-Pierre said the White House maintains full faith and support for the committee and is confident in its ability to complete the investigation.

"The position of the White House regarding Meadows's testimony is clear and laid out in our letter detailing the president's decision not to assert executive privilege," Jean-Pierre said. "As we wrote, the decision was made in recognition of these unique and extraordinary circumstances, where Congress is investigating an effort to obstruct the lawful transfer of power under our constitution."

Meadows's lawyer told the committee Tuesday that his client would no longer cooperate due to the committee's demands to view information protected by executive privilege and questions about unfair treatment. Meadows was the White House chief of staff at the time of the riot.

While Meadows has said he won't cooperate with the Jan. 6 inquiry, he delivered a trove of documents to the committee earlier this week. Meadows is one of a few dozen people subpoenaed as part of the congressional investigation into the events surrounding the siege of Congress.

The former Trump chief of staff told Fox News in a Tuesday evening interview that he has "tried to work with the committee to provide them — and even offered them other options in terms of answering questions."

Meadows said he would respect Trump's claim of executive privilege related to Jan. 6, claiming he is "not aware of anybody in the West Wing that had any advance knowledge that the security was going to be breached at the Capitol." The former president's assertion of executive privilege is being fought over in court.
