The House commission probing the January 6 attack on theU.S. Capitol issued a process Friday to Donald Trump, exercising its process power against the former President who lawgivers say is the “ central cause ” of a coordinated,multi-part trouble to capsize the results of the 2020 election.

The nine- member panel issued a letter toMr. Trump’s attorneys, demanding his evidence under pledge by November 14 and outlining a request for a series of corresponding documents, including particular dispatches between the former chairman and members of Congress as well as revolutionist groups.

We honor that a process to a former President is a significant and major action,” president Bennie Thompson andvice-chair Liz Cheney wrote in the letter toMr. Trump. “ We don’t take this action smoothly. ”

It’s unclear howMr. Trump and his legal platoon will respond to the process. He could misbehave or negotiate with the commission, advertise he’ll defy the process or ignore it altogether. He could also go to court and try to stop it.

The process is the rearmost and most striking escalation in the House commission’s 15- month disquisition of the deadly January 6, 2021 revolution, bringing members of the panel into direct conflict with the man they’ve delved from hence through the evidence of helpers, abettors and associates.

The commission writes in its letter that it has assembled “ inviting substantiation ” thatMr. Trump “ tête-à-tête orchestrated ” an trouble to capsize his own defeat in the 2020 election, including by spreading false allegations of wide namer fraud, “ trying to loose ” the Justice Department and by obliging state officers, members of Congress and his ownvice-president to try to change the results.But lawgivers say crucial details about whatMr. Trump was doing and saying during the siege remain unknown. According to the commission, the only person who can fill the gaps isMr. Trump himself.

The panel — comprised of seven Egalitarians and two Republicans — approved the process forMr. Trump in a surprise vote last week. Every member suggested in support.The day after,Mr. Trump posted a lengthy memo on Truth Social, his social media website, repeating his false claims of wide election fraud and expressing his “ wrathfulness, disappointment and complaint ” that the commission was n’t probing his claims. He made no citation of the process.
