The House committee investigating the Jan. 6, 2021 attack on the Capitol is expected to submit a court filing Wednesday laying out new details about the effort by conservative lawyer John Eastman to persuade Vice President Pence to intervene in the counting of electoral votes to help President Trump overturn the election.

The filing is intended to challenge Eastman’s claim that he should not be required to turn over thousands of emails the committee has requested — and is expected to show Eastman directly encouraged people in the government to not follow the Electoral Count Act, the 1887 law governing the congressional certification process, according to people with knowledge of the matter who, like others, spoke on the condition of anonymity because the filing has not been publicly released.

Eastman has so far submitted roughly 8,000 pages of emails to committee investigators but is withholding approximately 11,000 documents citing attorney-client privilege. Last month, a U.S. District judge in California ordered an expedited schedule to review Eastman’s bid to shield emails sent between Jan. 4 and Jan. 7.

The committee has disputed Eastman’s privilege claims on the basis that he has shown no evidence of a formal legal relationship with Trump, his White House or the Trump campaign.

To help make its case, the committee is expected to include in the filing details about Eastman’s efforts to pressure Pence, referencing testimony from two of Pence’s top aides, Marc Short and Greg Jacob, according to people with knowledge of the matter. The Pence aides explained in detail to the committee that Eastman led a pressure campaign against Pence, which they believed he was doing at Trump’s behest. Short, Pence’s chief of staff, along with Jacob, Pence’s counsel, were with the vice president during the assault on the Capitol.

Among the expected revelations is that after the violent pro-Trump mob left the Capitol and Congress reconvened to finish certifying Joe Biden’s victory, Eastman made a last-ditch effort in an email to Jacob to get the vice president to change his mind and not certify the results by committing a violation of the Electoral Count Act, according to people familiar with records and testimony provided to the committee.
