Amid Jan. 6 Revelations, Election Lies Still Dominate the G.O.P.

It was all a lie, the tales of stuffed ballot drop boxes, rigged voting machines, and constitutional “flexibility” that would have allowed Vice President Mike Pence to nullify the 2020 election results and send them back to Republican state legislatures.

The first three hearings of the House Jan. 6 committee have deeply undercut, if not demolished, the postelection myths repeated incessantly by former President Donald J. Trump and his supporters and embraced and amplified by Republicans in Congress.

A parade of Republican witnesses — his attorney general, William P. Barr, his daughter Ivanka Trump, and his own campaign lawyers — knew he had lost the election and told him so. Mr. Trump was informed that the demands he was making of Mr. Pence to block his defeat unilaterally were illegal. Even the most active coup plotter, the conservative lawyer John C. Eastman, conceded before Jan. 6 that his scheme was illegal and unconstitutional, then sought a presidential pardon after it led to mob violence.
