In addition to the Powell and Jenna Ellis videos, the Post got proffer videos from the other two defendants.

Although some of the recordings were garbled, the portions of the four statements that The Post was able to review — from Ellis, lawyers Kenneth Chesebro and Sidney Powell, and Georgia bail bondsman Scott Hall — offered many previously undisclosed details about the effort by Trump and his allies to reverse his defeat.

Chesebro disclosed in his recorded statement that at a previously unreported White House meeting, he briefed Trump on election challenges in Arizona and summarized a memo in which he offered advice on assembling alternate slates of electors in key battlegrounds to cast ballots for Trump despite Biden’s victories in those states. Chesebro’s recollection could provide evidence that Trump was aware of the elector plan.

The audible portions of the Fulton recordings reviewed by The Post do not appear to directly implicate Trump. At one point in Powell’s interview, she said Trump really believed he had won — a statement that could help his defense. But Powell also said that Giuliani spoke of a plan to gain access to voting equipment at a Dec. 18, 2020, meeting with Trump and others in the Oval Office. And Hall appeared to implicate another defendant, lawyer Robert Cheeley, describing Cheeley as part of the “brain trust” planning the Coffee County scheme. Giuliani spokesman Ted Goodman, asked to comment on the recordings, called the Fulton investigation a “farce” that should be dismissed immediately. A lawyer for Cheeley declined to comment.
