Sandy Pensler, a Republican businessman, abruptly withdrew from the U.S. Senate race and endorsed U.S. Rep. Mike Rogers during a rally with former President Donald Trump in Michigan. Pensler emphasized the importance of unity, aligning himself with Trump's policies and endorsing Rogers as a strong candidate for the GOP nomination. This move significantly narrows the Republican field, leaving Rogers as the frontrunner against contenders like Justin Amash and Sherry O'Donnell. Trump's endorsement of Rogers and the unification of the party were highlighted during the rally, indicating a shift in the dynamics of the Senate race in Michigan.
