An Arizona state lawmaker revealed Monday that federal authorities subpoenaed him for records related to the 2020 election, marking the second publicly confirmed jurisdiction the Department of Justice is investigating over the matter.
Arizona Senate President Warren Petersen, a Republican, said in a social media post he received the subpoena for material related to the state Senate’s 2020 audit last week and complied with it.
“Late last week I received and complied with a federal grand jury subpoena for records relating to the Arizona State Senate’s 2020 audit of Maricopa County,” Petersen wrote. “The FBI has the records. Any other report is fake news.”
The request represents an expansion of a federal probe tied to 2020 after the DOJ initially targeted Fulton County, Georgia. The development also comes as President Donald Trump has grown increasingly outspoken about election security in the lead-up to the 2026 midterms, renewing his attention on disputes stemming from the last presidential race.

Petersen made the revelation after President Donald Trump shared a Just the News report about the subpoena on Truth Social, writing, “Great!!! FBI secretly seizes election records from Arizona’s largest county as voting probe expands.”
Multiple U.S. officials confirmed the election probe to Fox News, saying the DOJ is looking at a large tranche of Arizona data from 2020 and 2024.

The White House directed Fox News Digital to the FBI on Monday when asked for comment. The FBI declined to comment.
Arizona Attorney General Kris Mayes, an elected Democrat, said the new investigation was based on claims that courts and state investigators have proven wrong.
“What the Trump administration appears to be pursuing now is not a legitimate law enforcement inquiry,” Mayes said in a statement. “It is the weaponization of federal law enforcement in service of crackpots and lies.”

The subpoena comes as the president increasingly focuses on election security ahead of the 2026 midterms, telling Congress in a social media post on Sunday that he will not sign any legislation into law until it passes the SAVE America Act.
The bill’s primary purpose is to require voters nationwide to show physical identification to prove citizenship to vote in federal elections. The version of the bill Trump is pushing would also ban mail-in ballots except for the military and in other extenuating circumstances.

Maricopa, Arizona’s most populous county, was a hotbed for accusations of voter fraud in 2020. Fulton County, Georgia, faced similar accusations, with the DOJ launching a separate investigation into the 2020 election earlier this year.
Trump lost Arizona in 2020 by about 0.3 percentage points. The president refused to concede, and his legal team brought a series of lawsuits alleging vote-counting irregularities, but none were successful.
