In the latest complaint, the NRSC alleged Dan J. Sullivan spent more than $5,000 after launching his campaign but failed to file the required Statement of Candidacy within the 15-day deadline, which the committee says expired on June 12.Dan J. Sullivan, who is not related to the incumbent senator, entered the race on May 29. In an earlier FEC complaint, the NRSC alleged he coordinated with Democratic strategist Amber Lee to launch his campaign in violation of federal laws prohibiting fraudulent misrepresentation. Last week, Alaska Division of Elections Director Carol Beecher deemed Dan J. Sullivan ineligible for the primary race, but he has since sued to stay in the race.

“Fraud Dan Sullivan’s disgusting contempt for Alaskans and complete disregard of the law is appalling,” the NRSC said in a statement. “Mary Peltola and her Democrat cronies want to rig this election because they can’t beat Dan S. Sullivan on his Alaska First record.”The filing marks the third complaint the NRSC has submitted over Dan J. Sullivan’s candidacy. The committee has also sent a letter to Alaska’s lieutenant governor and the state’s Division of Elections asking officials to remove him from the ballot, arguing his candidacy threatens the integrity of the Senate race.The dispute has injected controversy into one of the Democrats’ top Senate pickup opportunities in 2026. Former Rep. Mary Peltola is challenging Sen. Sullivan in a race that could help determine control of the Senate.
