Mariannette Miller-Meeks, an Iowa Republican who ran for Congress four times, is expected to be sworn in Sunday -- even as a challenge to her razor-thin, six-vote victory looms. Her journey to the House of Representatives has been longer and tougher than probably anyone else's in the 2021 freshman class, so her swearing-in -- albeit provisional -- is especially meaningful. "It has been a tumultuous, arduous journey to get here," Miller-Meeks said in a recent interview with Fox News.
