Nate Persily, a law professor at Stanford University, said that an executive order mandating changes to elections would be unconstitutional.

“The Constitution is clear on this. There are a lot of things where it’s ambiguous, but it doesn’t give unilateral regulatory authority for election to the president,” Persily said.

Persily pointed to Trump’s desire to nationalize elections and the FBI’s recent seizure of ballots and voter records from Fulton County, Georgia, as Trump continues to make false claims that he won the 2020 election.

“It’s not an isolated tweet here, right?” Persily said of Trump’s posts Friday. “There’s a lot that’s going on. So you’ve got the action in the legislature, in Congress, you’ve got these, the earlier executive order, you have the seizing of the ballots and other materials from Fulton County, right? And so it’s all of a piece with the desire to have greater federal oversight of elections.”
