Republican Senate candidate Dan Bongino begins airing the first radio advertisement of his campaign today, a largely introductory spot that focuses on his outsider status and criticizes “career bureaucrats.”

Bongino narrates the minute-long ad, which the campaign said begins airing on WCBM in Baltimore today.

“Can we all agree that politicians aren’t getting the job done?” the former U.S. Secret Service agent asks in the ad. “I refuse to accept that the current crop of D.C. bureaucrats is the best we can do.”

Bongino is running against nine other Republicans in the April 3 primary, including former Pentagon official Richard J. Douglas. The winner will likely face incumbent Sen. Ben Cardin in November.
