A Republican named Dan Sullivan is running against incumbent Republican Sen. Dan Sullivan for his Alaska Senate seat, and party officials are challenging the candidacy as an effort to help Democrat Mary Peltola.

The National Republican Senatorial Committee (NRSC) filed a complaint with the Federal Election Commission (FEC) on June 9. Alaska Lt. Gov. Nancy Dahlstrom, a Republican who oversees state elections, opened an investigation on June 8 into the challenger’s declaration of candidacy.
