Congress is just beginning a new investigation into the Jan. 6 riot at the Capitol, but the movement behind it remains as active as ever.

Former President Donald Trump is frequently repeating claims of victory, plotting revenge against politicians who opposed his efforts to overturn the election, attacking key Republicans who refuse to back him up now and hinting at a return to power, either through another presidential run or some other means.

There’s no legal avenue for Trump to reverse the 2020 results. But a half-dozen scholars who study democracy and election laws told NBC News they are increasingly worried that 2024 could be a repeat of 2020, only with a party further remade in the former president’s image and better equipped to sow disorder during the process and even potentially overturn the results.

“Obviously the insurrection was horrific in its violence and assault on democracy, but it didn't disrupt the true winner of the election,” said Edward B. Foley, a professor at Moritz College of Law at Ohio State University who researches election law. “What you don’t want is it to have been a rehearsal.”
