WASHINGTON, (Reuters) – The Democratic-led U.S. House of Representative Select Committee investigating the Jan. 6th, 2021 attack on Capitol has been working for nearly a year. It interviews witnesses and gathers documents in preparation of the public hearings that will begin on June 9.

These are the facts:

MULTIPLE DATES

In an attempt to prevent formal certification of Donald Trump’s defeat in the election, thousands of Trump supporters attacked the building. This caused millions in damages. On the morning of the attack, four people were killed and one Capitol Police officer was injured in the fight against the rioters. Since then, four officers died and 140 were hurt.

THE COMMITTEE

The committee is composed of nine members from the House. It was created by Nancy Pelosi, Democratic House Speaker, on July 1, 2021 after Republicans stopped creating a bicameral commission.

The panel includes Representative Bennie Thompson (the chairperson), as well as representatives Zoe Lofgren and Elaine Luria as Adam Schiff and Pete Aguilar.

For their participation, the Republican National Committee censured the two Republicans who were on the panel: Representatives Liz Cheney (vice chairperson) and Adam Kinzinger.

The RNC never previously censured any Republican in Congress.

THE PROBE

More than 1000 interviews and depositions were conducted by the committee with its many investigators. The majority of those interviewed are not identified. However, Trump’s close advisor and daughter, Ivanka Trump and Jared Kushner are known to have been present. Rudy Giuliani is Rudy Giuliani.

In order to obtain documentation and compel testimony, the committee declared that 99 subpoenas had been issued. However, it is not known if there have been more.

The most prominent subpoenas sent have been to Mark Meadows who is a former representative and served as Trump White House chief-of-staff; Stephen Bannon, a Trump adviser; Roger Stone, an operative Republican; Trump’s child Eric; the major social media platforms; and members of Oath Keepers and Proud Boys groups which backed Trump.

It now has a collection of over 140,000 documents. 472 tips were received from the tipline.

CONTEMPT OF THE CONGRESS

Four Trump associates were charged for contempt by Congress after the House voted in favor of them. Trump exhorted former aides not to comply with subpoenas from the committee.

Bannon, Meadows, and ex-top Trump administration aides Peter Navarro, were referred by the House to the Department of Justice. They will decide whether or not to press criminal charges. The penalties include up to a year in prison and a fine of up to $100,000.

Justice recommended that Bannon and Navarro be tried in a case due to begin in July. The Justice did not indict Meadows and Scavino.

Jeffrey Clark was also recommended by the committee to be charged. Clark was a high-ranking official in Justice Department during Trump’s administration. After Clark took a deposition and agreed to the charges, no vote was taken by the full House.

CRIMINAL PROSECUTIONS

Nearly 800 people were arrested in connection to the Capitol breach, with more than 250 being charged with impeding or assaulting law enforcement.

A total of nearly 300 have pled guilty to federal charges.
