Washington: In a major escalation of their sprawling inquiry, lawmakers probing the 2021 attack on the US Capitol subpoenaed former president Donald Trump Friday to testify on his involvement in the violence.
The summons came after the House panel of seven Democrats and two Republicans voted unanimously last week to compel Trump's appearance before investigators.
It requires the 76-year-old Republican to produce documents by November 4 and to appear for a deposition beginning on or around November 14 -- the Monday after the crucial November 8 midterm elections.
"As demonstrated in our hearings, we have assembled overwhelming evidence, including from dozens of your former appointees and staff, that you personally orchestrated and oversaw a multi-part effort to overturn the 2020 presidential election and to obstruct the peaceful transition of power," the committee told Trump in a letter.
Trump, who urged his supporters to "fight like hell" in a fiery speech near the White House on January 6, 2021, was impeached for inciting the mob to storm Congress later that day to halt the peaceful transfer of power to Joe Biden.
The letter accuses Trump of bidding to overturn the election despite knowing claims of fraud had been overwhelmingly rejected by more than 60 courts and refuted by his campaign staff and senior advisors.
Without confirming Trump had received the subpoena, his lawyer David Warrington said his team would "review and analyze" the document and "respond as appropriate to this unprecedented action."
The White House declined to comment on the matter but offered the broad statement that it is "important to get to the bottom of January 6."
Trump is notorious for his ability to run down the clock on congressional investigations and legal action, and it remains highly unlikely that he would agree to give evidence.
The subpoena expires in any case with the new congressional term in January. Republicans are expected to win back the House of Representatives in November's elections and plan immediately to end the investigation.
But the move marks an aggressive escalation of the probe, which has issued more than 100 subpoenas and interviewed more than 1,000 people since its launch in 2021.
While no sitting president has ever been forced to testify before Congress, lawmakers have summoned several former presidents to discuss their conduct in office.
Trump's compliance would mean testifying under oath and could result in being charged with perjury were he to lie.
If he refuses to comply, the full House can hold him in criminal contempt in a vote recommending him for prosecution.
