The advisors working with former President Donald Trump after the 2020 presidential election “were basically snake oil salesmen,” Marc Short said on Sunday’s Meet the Press, leading Trump to believe that there was some way former Vice President Mike Pence could overturn the results.

Short served as Pence’s chief of staff, and was with him at the Capitol during the Jan. 6 attack. During an address on Friday to the conservative Federalist Society, Pence pushed back at Trump’s false assertion that he could have decided the election, saying, “President Trump is wrong.” Short backed Pence up on Meet the Press, telling host Chuck Todd that Pence made it clear from the beginning he could not overturn the election and never intended to delay certification of the results.

Trump, Short continued, “had many bad advisers, who were basically snake oil salesmen giving him really random and novel ideas as to what the vice president could do. But our office, you know, researched that and recognized that was never an option.” Short added that he didn’t know if Trump sought out this advice because it’s what he wanted to hear.

Short went on to say that he thinks the House select committee investigating the Jan. 6 Capitol attack is “partisan,” but he testified before its members because he was subpoenaed. “I don’t know how often you’ve been subpoenaed, Chuck, and if you view that as cooperation, but I view that as following the law,” he said.
