The commission plans to move away from the theory that Trump’s lawyer, John Eastman, said Pence had the power to overturn the election results through Trump’s weekly campaign that led to the uprising. Aides said the hearing would include new material on what Pence did on Jan. 6, including his whereabouts. The commission’s aides said they also intended to demonstrate at the hearing that there was a “continuing threat” to democracy from those who held the false impression that the 2020 election was rigged. Greg Jacob, who served as Pence’s adviser when he was vice president, and J.P. Retired judge and informal Pence adviser Michael Lutig will testify before the commission on Thursday. While Pence’s former chief of staff, Marc Short, did not testify on Thursday, his aides said his deposition was expected to be filed. Much of Thursday’s presentation will be by Democrat Pete Aguilar of California. A committee adviser will also ask questions during Thursday’s hearing. The commission’s aides said the commission was once again planning to combine live witness testimony with video’s testimony. On Tuesday, the commission teased a video of Trump’s former White House attorney, Eric Hersman, saying he had told Eastman on Jan. 7 that he should “get a great lawyer to defend the crime.” This story has been updated with additional developments on Wednesday.
