Official notice from the House Select Committee investigating the Jan. 6, attack on Capitol was released. It stated that the hearing will be held on Thursday, June 9, at 8 p.m. Prime time. ET.

The notice, which was posted late Thursday night, also stated that witnesses would be announced next week.

The hearing will see the panel “present previously unseen materials documenting January 6, witness testimony, preview additional hearings and give the American people a summary its findings about the coordinated multi-step effort by the American people to overturn the results from the 2020 presidential election, and prevent the transfer or power transfer.”

This will be the committee’s first public hearing in almost a year. In July, four officers from police gave graphic accounts of the verbal and physical assaults they suffered while protecting the Capitol. They also spoke out about the legislative gatherings on Jan. 6, 2021 to count and certify the electoral votes of the 2020 election. Pro-Trump rioters invaded the Capitol and injured more than 100 law enforcement officers, causing several deaths.

The panel will hold approximately a dozen public hearings in June, and then release its report in September. The committee members believe the hearings will give a story about the events leading up to the attack and who funded some of the groups that promoted false claims that Joe Biden didn’t win the election. They also discuss what happened behind the scenes during the violent insurrection.

The committee has been holding several business meetings in recent months to approve contempt charges against some former Trump administration officials, who have refused to cooperate with the investigation.

Former White House Chief of Staff Mark Meadows initially agreed to a subpoena. He turned over emails and text messages, but then changed his mind and refused to appear or provide additional documents. The panel also subpoenaed former aides Steve Bannon and Peter Navarro. The House unanimously approved contempt charges against all four of them and referred them to Justice Department. Bannon has been indicted by DOJ for not complying with a congressional subpoena. His trial is scheduled for this summer.

Since its creation, roughly one year ago, the committee has interviewed over 1,000 witnesses and subpoenaed approximately 100 people.

Initial leaders of both parties called for an independent, outside commission to investigate the riot. However, Republican members voted against that effort and also opposed the creation of the select committee. After the committee was approved, Kevin McCarthy, R.-Calif., appointed five members of his party to its board. McCarthy resigned from the panel after Nancy Pelosi (D-Calif.), rejected three of them. Pelosi appointed Liz Cheney from Wyoming and Adam Kinzinger from Illinois to the committee.

McCarthy and five other House Republicans were subpoenaed by the committee to answer questions about their communications with Trump. They have declined to appear before it.

Although the panel is not authorized to bring criminal charges against the former President or any other person involved in the events leading to or on the day after the attack, several panel members believe that the Justice Department could still take action without the report of the panel.
