Trump’s interest has been fueled by conversations he has had with an array of figures who have publicly touted false claims of election fraud. Among them, according to advisers, is Christina Bobb, a host at the One America News network who has privately discussed the Arizona audit with the former president and his team; Mike Lindell, the chief executive of the company MyPillow; and Pennsylvania state Sen. Doug Mastriano (R), who urged the state’s congressional delegation to reject Biden’s victory there last fall. Trump has become so fixated on the audits that he suggested recently to allies that their success could result in his return to the White House this year, according to people familiar with comments he has made. Some advisers said that such comments appear to be just offhand musings... Advisers say he voraciously watches any television coverage he can find of the Arizona recount and reads “everything he can get his hands on” about the audits, according to one person who speaks to Trump frequently. And he has made supporting his claims of a stolen election — or at least remaining silent about them — a litmus test of sorts as he decides whom to endorse for state and federal contests in 2022 and 2024. Talk by Trump and his supporters of overturning the election was revived in late April when an audit of the results in Arizona’s largest county ordered by the Republican state Senate began.
