ON THE EVENING of January 6, 2021 — as the Capitol Police were doing final sweeps of ransacked buildings and senators were preparing to resume the electoral vote count — former President Donald Trump asked the White House switchboard to get Mark Martin on the phone.

A retired North Carolina Supreme Court justice, Martin was a key adviser to Trump’s multi-pronged fight to overturn his loss in November 2020. In discussions with aides and administration officials, Trump considered Martin’s counsel as important as that of attorney John Eastman, who’s currently under indictment in two states and may be disbarred in a third. Trump so trusted Martin that another legal adviser name-dropped him to bolster his own pitches.

As another election looms, one that is shaping up to be settled by courts, it’s crucial to examine the legal players who tried to reverse Trump’s defeat in 2020. But unlike Eastman and other Trump-aligned lawyers, Martin has largely escaped scrutiny for his contribution to the Big Lie effort, which culminated in a nine-minute call as Trump and his allies were still looking for ways to pressure former Vice President Mike Pence into handing Trump the election.
