Former White House chief of staff Mark Meadows said that the National Guard would be available to protect pro-Trump people during their Jan. 6 gathering at the U.S. Capitol, according to information released Sunday by the House panel investigating the deadly insurrection.

Meadows shared those plans in an email that he sent to an unidentified person ahead of the days violence, the Associated Press reported, citing a report from the panel. He also said that additional guards would be placed on standby.

The panel is set to vote on potential contempt charges for Meadows after he failed to comply with a congressional subpoena related to the investigation. It did not publicly release the full email and other documents, but described some of what it obtained from the Trump insider. As part of the investigation, Meadows has provided 6,600 pages of records taken from personal email accounts and about 2,000 text messages, according to the AP.
