WASHINGTON, DC, United States (AP) — The House committee investigating the January 6, 2021 riot at the US Capitol has postponed a hearing that was to feature dramatic testimony from former Justice Department officials who were pressured by then-President Donald Trump to pursue his false election fraud theories.

The hearing had been scheduled for Wednesday, but the committee on Tuesday morning said that it had been postponed. It did not give a reason or a new date for the hearing.

Zoe Lofgren, a member of the committee, described the postponement as “no big deal” during an appearance on MSNBC’s Morning Joe and said the delay was the result of “technical work” that still needed to be done.

“Putting together the video exhibits is an exhausting exercise for our very small video staff,” said Lofgren, a California Democrat. “We were going to have one-two-three in one week and it’s just — it’s too much to put it all together. So we’re trying to give them a little room to do their technical work.”

The next hearing is set to take place on Thursday.

The witnesses at Wednesday’s hearing were to include Jeffrey Rosen, who was the acting Attorney General at the time of the Capitol insurrection, as well as two other former top officials at the Justice Department, Richard Donoghue and Steven Engel. Lawyers for all three men did not immediately return messages seeking comment.

The witnesses, all of whom have since left the Justice Department, are expected to testify about how Trump sought to bend the department to his political will during the final days of his Administration by urging officials to declare the election as corrupt and to aid in his efforts to challenge the results of the race won by Democrat Joe Biden.

Though the lawyers’ accounts have been documented by the news media, the hearing — whenever it occurs — will give the American public its most detailed glimpse of a near-revolt inside the Justice Department as Trump contemplated replacing the agency’s top official with a lower-level lawyer seen as more willing to advance the president’s false claims that the election was stolen. Several other senior officials warned Trump in a White House meeting that they’d resign if the leadership change occurred.

Rosen took over the department following the December 2020 departure of William Barr, who angered Trump by saying the department had not found fraud that could have affected the results of the election. Trump quickly soured on Rosen, too, after the then-acting Attorney General rejected entreaties from the president and the White House to challenge the election results.

Around that time, the president was introduced to Scott Perry, a Pennsylvania Republican and ardent Trump backer, to Jeffrey Clark, a little-known assistant Attorney General who postured himself as willing to advance Trump’s baseless voting fraud claims.

At one point, according to testimony provided to lawmakers, Clark presented colleagues with a draft letter pushing Georgia officials to convene a special legislative session on the election results. Clark wanted the letter sent, but superiors at the Justice Department refused.

A lawyer for Clark did not immediately return a phone message on Wednesday.

Clark’s support led Trump to openly contemplate naming him as acting Attorney General in place of Rosen.

The situation came to a head during a tense, hours-long January 3, 2021 meeting at the White House in which Engel and Donoghue told Trump that they would resign from the Justice Department if Trump proceeded with his plan to fire Rosen and replace him with Clark. Trump ultimately relented, and Rosen remained on as acting Attorney General through the end of the Administration.
