In the weeks after the 2020 election, retired Gen. Michael T. Flynn, Donald J. Trump’s former national security adviser, was a key figure in efforts to subvert the election outcome. In recent interviews and speeches, he and an associate are warning that this year’s election will be stolen from Mr. Trump, advising supporters to take action to prevent a theft and vowing retribution once Mr. Trump is back in power.
At the Rod of Iron Freedom Festival, a far-right event in Pennsylvania this month, Mr. Flynn told the crowd that after a Trump victory: “Katie, bar the door. Believe me, the gates of hell — my hell — will be unleashed.”
