Arizona Attorney General Mark Brnovich, a Republican, is leaning toward challenging Democratic Sen. Mark Kelly in 2022 after initially moving toward a run for governor.

Brnovich, 54, has won two statewide elections in Arizona, which means he has survived two Republican primaries — including one since former President Donald Trump came to dominate the party. The attorney general’s supporters believe those results are proof he can attract support from disparate wings of the GOP and make him the ideal candidate to run against Kelly in the general election.
