DES MOINES, Iowa (AP) — High-ranking Senate Democrat Ron Wyden has alleged that Health Secretary Robert F. Kennedy Jr. broke the law with recent phone calls urging third-party candidates to drop out of two Iowa congressional races.In a complaint to the U.S. Office of the Special Counsel filed Monday, Wyden requested an investigation into whether the June calls violated the Hatch Act, a 1939 law that restricts certain political activities by federal employees. The Oregon Democrat said Kennedy acted inappropriately by interfering with elections that Trump’s Republican administration wants GOP candidates to win.“Kennedy has spent sixteen months using his official position to undermine the health and well-being of his fellow Americans, and now he is using his official position to undermine the integrity of democratic elections too,” reads a statement from Wyden, the ranking member of the Senate Finance Committee, which plays a role in overseeing the nation’s health agencies.The accusation comes as Trump has dispatched Kennedy to swing districts around the country as a key surrogate for the administration, promoting its widely popular efforts to encourage healthy eating and exercise. It takes issue with another task Kennedy reportedly did on behalf of the administration: calling Libertarian candidates to push them to drop out of two races where they could be spoilers for GOP candidates. At stake is control of Congress in a competitive midterm election year, where any win could be decisive in shaping the next two years of federal policy.Spokespeople for Kennedy and the U.S. Department of Health and Human Services didn’t immediately respond to a request for comment.
