The National Republican Senatorial Committee has asked the Federal Election Commission to investigate Dan J. Sullivan, a Republican Senate candidate in Alaska who shares the same name as incumbent Sen. Dan Sullivan (R-AK), alleging that his campaign is a deliberate attempt to mislead voters.

Newcomer Sullivan’s candidacy has injected controversy into one of the Democrats’ top Senate targets of 2026, where former Rep. Mary Peltola is mounting a well-funded challenge against Sen. Sullivan as Democrats look for paths to reclaim the Senate majority.
