WASHINGTON (AP) The House Jan. 6 committee has interviewed former Treasury Secretary Steven Mnuchin and is in negotiations to talk to several other former members of Donald Trump s Cabinet as it scrutinizes the days after the Capitol insurrection and discussions about whether to try and remove the then-president from office.

The negotiations come as the committee was interviewing Trumps onetime chief of staff, Mick Mulvaney, on Thursday. The former South Carolina congressman held that job until 2020 and later was special envoy for Northern Ireland, a post he resigned immediately after the riot on Jan. 6, 2021.

The interviews and negotiations were confirmed by three people familiar with the committees work who were not authorized to discuss the developments publicly and spoke on condition of anonymity.

The committee asked Mnuchin about discussions among Cabinet secretaries to possibly invoke the constitutional process in the 25th Amendment to remove Trump after the attack on the Capitol, according to one of the people, and is in active talks to interview former Secretary of State Mike Pompeo. Pompeo is likely to appear in the coming days, the person said.

The committee had already interviewed former acting Attorney General Jeffrey Rosen, former Labor Secretary Eugene Scalia and former acting Defense Secretary Christopher Miller as it focuses on Trump and what he was doing in the days before, during and after the riot.
