Rep. Elise Stefanik (R-N.Y.), who was recently elected as the House Republican Conference chair, said the Department of Justice’s questions about the Maricopa County, Arizona, audit of the 2020 election may be unconstitutional.

On May 5, the Justice Department sent a letter to Arizona Senate leader Karen Fann, a Republican, inquiring about the custody of the ballots under review by a group of private contractors, alleging that the group’s other processes—including the canvassing of addresses—could be considered “voter intimidation.”

“I support that audit,” Stefanik said after being asked about it in a Fox Business interview on May 16.

“Transparency is good for the American people. And again, this should be a nonpartisan issue, whether you are Republican, Democrat, independent, or conservative, transparency is important, and the audit was passed by the Arizona state Senate.”

Stefanik later said that the “Biden Department of Justice is trying to block that audit,” which, she said, “is unconstitutional from my perspective.”

“Our states, constitutionally, are responsible for writing states’ constitution law,” she said.

Pamela Karlan, principal deputy assistant attorney general with the Justice Department’s Civil Rights Division, wrote to Fann that “the proposed work of the audit raises concerns regarding potential intimidation of voters.”

Fann replied that the plan by election auditors to verify the validity of certain voters had been placed on hold.

“If and to the extent the Senate subsequently decides that canvassing is necessary to the successful completion of the audit, its vendor will implement detailed requirements to ensure that the canvassing is conducted in a manner that complies fully with the commands of the United States Constitution and federal and state civil rights laws,” Fann wrote earlier this month.

Stefanik’s comments on May 16 came just days after Dominion Voting Systems and Maricopa County officials said they wouldn’t provide passwords for election machines in Maricopa County. Dominion said it would comply with the audit, but that Cyber Ninjas – the company hired by the Arizona state Senate – isn’t accredited by the U.S. Election Assistance Commission.

The Department of Justice didn’t respond to a request for comment by press time.

Stefanik was approved last week in a vote by House Republicans to become the Republican Conference chair—the party’s No. 3 position in the House. She took over after GOP lawmakers voted to remove Rep. Liz Cheney (R-Wyo.), a frequent critic of former President Donald Trump, from the position.

Stefanik received support from Trump as well as other House GOP leaders.
