Sheriff Mark Lamb of Pinal County, Arizona, a strong advocate for border security, is running for U.S. Senate in 2024.

If Lamb wins the Republican nomination, he will face off against incumbent Arizona Sen. Kyrsten Sinema, a former Democrat who left the party to become an independent last year.

“Arizona needs a proven conservative fighter that’s going to stand up for the people of Arizona, and honestly, that’s going to fight for the values that we espouse, which is God, family, [and] freedom,” he told The Daily Signal.
