WASHINGTON (AP) The 1/6 committee is set to plunge into Donald Trump s last-ditch effort to salvage the 2020 election by pressuring Vice President Mike Pence to reject the electoral count a highly unusual and potentially illegal strategy that was set in motion in the run-up to the U.S. Capitol riot .

With two live witnesses Thursday, the House panel intends to show how Trumps false claims of a fraudulent election left him grasping for alternatives as courts turned back dozens of lawsuits challenging the vote.

Trump latched onto conservative law professor John Eastmans obscure plan and launched a public and private pressure campaign on Pence days before the vice president was to preside over the Jan. 6 joint session of Congress to certify Joe Biden s election victory. A federal judge has said it is more likely than not Trump committed crimes over the scheme.

The illegality of the plan was obvious, the Jan. 6 panel said in a court filing against Eastman .

The committee will hear from Greg Jacob, the vice presidents counsel who fended off Eastmans ideas for Pence to carry out the plan; and retired federal judge Michael Luttig, who called the plan from Eastman, his former law clerk, incorrect at every turn.

Thursdays session is also expected to divulge new evidence about the danger Pence faced that day as the mob stormed the Capitol shouting hang Mike Pence ! with a gallows on the Capitol grounds as the vice president fled with senators into hiding. Nine people died in the riot and its aftermath.
