WASHINGTON, Nov. 12 (Xinhua) -- Former U.S. President Donald Trump filed a lawsuit against the House select committee investigating last year's Capitol riot.
The lawsuit sought to block enforcement of a subpoena seeking Trump's testimony and documents tied to the incident on Jan. 6, 2021, and its causes.
Trump's lawyers argued that the Republican has "absolute testimonial immunity" and that the committee lacked the constitutional authority to issue the subpoena.
The subpoena to Trump last month requires the production of documents to the House panel by Nov. 4 and to appear for deposition testimony beginning on or about Nov. 14.
Trump has repeatedly lashed out at the committee and its members made up of seven Democrats and two Republicans.
On Jan. 6, 2021, a large crowd of Trump supporters stormed the Capitol in Washington, D.C., and disrupted a joint session of Congress to affirm the 2020 presidential election results.
Approximately 140 police officers were assaulted. Authorities have linked at least five deaths to the mayhem.
It was the worst attack on the U.S. Congress in more than 200 years, which led to Trump's second impeachment by the House of Representatives shortly before his term officially ended. ■
