Pennsylvania state Sen. Doug Mastriano went out of his way to help advance former President Donald Trump’s election lies: He spearheaded a “hearing” at a hotel in Gettysburg a few weeks after the 2020 election, where Trump and his lawyer Rudy Giuliani made false claims about election fraud. He chartered buses to ferry his supporters to Washington on January 6. And he was briefly in charge of the Pennsylvania state Senate’s partisan “audit” of the 2020 election.
