Constitutional law professor Alan Dershowitz said President Trump has a limited number of strategies to change the results of the 2020 election.

During an interview with Fox News’s Maria Bartiromo on Sunday, Derschowitz, who defended Trump during his impeachment trial earlier this year, said there are a maximum of three “legal, constitutional paths” to victory. However, he added the president’s legal team will face a variety of challenges that he thinks will likely prevent the results from being overturned.
