Arizona House Speaker Rusty Bowers asked former President Donald Trump and his attorneys for evidence of their claims that undocumented immigrants and dead people voted in the 2020 election.

But he was told by Trump's attorney Rudy Giuliani, "We've got lots of theories, we just don't have the evidence."

Bowers testified Tuesday to the U.S. House select committee investigating the Jan. 6 insurrection.

– In his 40 minutes as a witness, he provided somber, measured testimony about attempts by Trump and his allies to persuade him to decertify Arizona's electoral votes for Joe Biden and to replace them with Trump electors.

– Trump and Giuliani alleged that there had been massive election fraud in Arizona, claiming that 200,000 undocumented immigrants and 5,000-6,000 dead people had cast ballots in the state.

Neither Trump nor anyone from his campaign ever provided any evidence of fraud, Bowers said.

Bowers said Republican U.S. Rep. Andy Biggs called him on the morning of Jan. 6, 2021, and asked him to support the decertification of Arizona's Biden electors.

Bowers said he was unfamiliar with any state or federal law that would permit the electors to be replaced, and that to do so would violate his oath of office.

– He said he rejected the request to call an official legislative hearing because he "didn't want to be used as a pawn."
