Donald Trump sued the House Select Committee Investigating the Jan. 6 Attack on the U.S. Capitol on Friday in an effort to quash a congressional subpoena.
Trump had a Nov. 14 deadline to testify and turn over documents. After he was subpoenaed, Trump announced he would make a "very big announcement" at Mar-a-Lago on Nov. 15.
On Friday evening, his attorneys announced he would fight the subpoena in federal court in West Palm Beach, Florida.
The 41-page filing was signed by Matthew Sarelson of the Dhillon Law Group.
"The separation of powers concerns raised by congressional aggrandizement at the expense of the Executive Branch do not expire when a President leaves office," the filing argued.
After claiming Trump had attempted to accommodate the select committee while refusing to comply with the subpoena, the filing said, "the Committee, however, insists that the Executive, in the person of President Trump, must yield to the demands of the Legislative Branch and comply with its Subpoena."
Trump's lawyers concluded the subpoena was invalid.
When issuing the select committee's subpoena, Chairman Bennie Thompson (D-MS) and Vice Chair Liz Cheney (R-WY) explained what they were seeking to learn its letter to Trump.
“You took all of these actions despite the rulings of more than 60 courts rejecting your election fraud claims and other challenges to the legality of the 2020 presidential election, despite having specific and detailed information from the Justice Department and your senior campaign staff informing you that your election claims were false, and despite your obligation as President to ensure that the laws of our nation are faithfully executed," the two wrote. "In short, you were at the center of the first and only effort by any U.S. President to overturn an election and obstruct the peaceful transition of power, ultimately culminating in a bloody attack on our own Capitol and on the Congress itself.”
