The campaign arm of the Senate Republicans made a hefty ad buy in Nebraska to help boost incumbent Sen. Deb Fischer in her race against independent challenger Dan Osborn.
Ad tracking company AdImpact said in an X post Thursday that the National Republican Senatorial Committee placed an ad-buy worth $172,000 in conjunction with Fischer's campaign.
An NRSC spokesman said in a statement that shadowy Democrat groups were "dumping millions" of dollars into the race in a bid to unseat Fischer. NRSC Communications Director Mike Berg said, "The NRSC will help Trump-endorsed Deb Fischer fight back against the left-wing smear campaign national Democrats are waging against her."
Fischer is seeking her third term in bright red Nebraska, but is facing a tougher-than-expected competition from Osborn, who's running as an independent.
Osborn is a union mechanic and a political newcomer who's been endorsed by the United Auto Workers and other labor organizations.
There are few polls tracking the Nebraska Senate race, but recent surveys have shown it to be neck and neck, with Fischer ahead in one poll and Osborn leading in another.
Still, major pollsters like The Hill's Decision Desk gives Fischer a 96% chance of winning in November.
Nebraska hasn't elected a non-Republican senator since 2006.
