Arizona lawman Joe Arpaio reminded everyone why he’s considered “America’s toughest sheriff” when he took a Fox News anchor to task in a live interview this afternoon.

Appearing on “America Live” with Megyn Kelly, Arpaio told Kelly she was wrong in some of her reporting about a federal investigation into his treatment of Hispanics in Maricopa County, Ariz.

The U.S. Justice Department is looking into allegations of racial profiling, a charge Arpaio denies, and the federal government wants Arpaio to allow an independent monitor to oversee the conduct of his office.

The Obama administration announced it’s now preparing to sue Arpaio. The Justice Department has said negotiations have broken down with the sheriff, who also believes President Obama’s birth certificate and Selective Service card are likely forgeries.

Though Kelly never mentioned concerns over Obama’s eligibility in her interview, she did ask Arpaio why it would be a deal-breaker to have a federal monitor in his presence to make sure everything in his county office were “legit.”
