The House select committee investigating the Jan. 6 attack on the Capitol on Monday subpoenaed Donald Trump's former aide Roger Stone, Info Wars host Alex Jones and former Trump spokesman Taylor Budowich in its ongoing investigation of the failed insurrection at the Capitol building.

“We believe the witnesses we subpoenaed today have relevant information and we expect them to cooperate fully with our effort to get answers for the American people about the violence of January 6th,” said select committee chairman Rep. Bennie Thompson, D-Miss., in the press release.

The subpoenas come after the committee has interviewed more than 200 witnesses.

“We need to know who organized, planned, paid for and received funds related to those events, as well as what communications organizers had with officials in the White House and Congress,” Thompson added.

According to the committee, Jones had allegedly helped organize the rally near the White House, which was helped with 80% of funding provided by the heiress to a Florida-based supermarket chain.

Budowich had allegedly helped advertise the rally outside the White House. His efforts included “directing to the 501(c) (4) organization approximately $200,000 from a source or sources that was not disclosed to the organization to pay for the advertising campaign,” according to the committee.

Stone had promoted his presence at rallies on Jan. 5 and 6. and sought support to pay for security.

In a statement, Stone denied involvement in the Jan. 6 attack.

“Any statement, claim, insinuation, or report alleging, or even implying, that I had any involvement in or knowledge, whether advance or contemporaneous, about the commission of any unlawful acts by any person or group in or around the U.S. Capitol or anywhere in Washington, D.C. on January 6, 2021, is categorically false,” Stone said.

The House has also issued a subpoena for Dustin Stockton and Jennifer Lawrence, a couple who have actively pushed the false narrative the election was stolen from Trump. The committee letters cite the couple's work with Women for America First, a right-wing activist group.

The panel has issued 40 subpoenas. Other Trump aides, such as White House chief of staff Mark Meadows and White House chief strategist Steve Bannon, were recently subpoenaed.
