The House Select Committee to Investigate the January 6th Attack on the United States Capitol Monday announced that it has issued subpoenas to Rudy Giuliani, Jenna Ellis, Sidney Powell, and Boris Epshteyn.

Committee Chairman Bennie G. Thompson (D-MS) explained the subpoenas, saying:

The four individuals we’ve subpoenaed today advanced unsupported theories about election fraud, pushed efforts to overturn the election results, or were in direct contact with the former President about attempts to stop the counting of electoral votes. We expect these individuals to join the nearly 400 witnesses who have spoken with the Select Committee as the committee works to get answers for the American people about the violent attack on our democracy.

Giuliani is specifically accused of meeting with state legislators to convince them to overturn election results and encouraging President Trump to seize voting machines from around the country.

Ellis and Epshteyn responded to the news on Twitter. Ellis re-shared a tweet from November 2020, in which she said to opponents, “Do your worst. I’m not intimidated. I won’t back down. My mission is Truth, my God is the Lord Jesus Christ, and my client is the President of the United States.”

In a statement, Epshteyn called the Committee “illegitimate” and criticized its “Stalinist witch hunt against President Trump and his supporters.” Epshteyn said he would be happy to share information about election fraud with the Committee or “anyone else.”

The recipients must produce documents by February 1, 2022, and appear for deposition before Congress on February 8, 2022.

Fellow Trump ally Steve Bannon was held in contempt of Congress in November 2021 after failing to respond to his subpoena or attend his scheduled deposition.
