President-elect Donald Trump brought a lawsuit against longtime pollster Ann Selzer, her firm, and the Des Moines Register on Monday over claims they attempted to interfere with the 2024 election.

Trump accused Selzer, a highly regarded Iowa-based pollster of more than 20 years, of intentionally skewing a poll in favor of Vice President Kamala Harris days before the election and failing to capture Trump’s decisive 13-point victory in the state.
