The House committee investigating the Jan. 6 riot at the U.S. Capitol has the "receipts" on former White House chief of staff Mark Meadows, according to one reporter.

CNN's Jamie Gangel talked to anchor Jake Tapper to preview the panel meeting Monday evening to vote on holding the former Trump aide in contempt after he stopped cooperating with its investigation.

Members of the panel will also present "significant new information," Gangel said.

"Mark Meadows was in the room on Jan. 6, and the committee has a lot of the receipts," she said. "Jake, a source familiar tells me that, among the communications and texts and emails, the committee is going to simply lay out how much was going on in real time: what Meadows knew, who was speaking to him — a Republican loyalist, White House officials — and that we're going to see those actual texts."

Meadows sued members of the Jan. 6 committee and House Speaker Nancy Pelosi last week, asking the court to invalidate the two subpoenas he received. He argues that many of his communications are protected by executive privilege.

The contempt statute “has never been used to prosecute one of the president’s most senior aides who declined to appear and give testimony under compulsion by Congress,” Meadows’s attorney, George Terwilliger, wrote in a Monday letter to the select committee, the Wall Street Journal reported.

Before he stopped cooperating with the panel and did not show up for a deposition, Meadows provided roughly 9,000 pages of documents, according to the panel. Among them are "real-time communications with many individuals as the events of January 6th unfolded," Chairman Bennie Thompson and Vice Chairwoman Liz Cheney said in a joint statement.
