Gallagher says he won't run for Congress again after refusing to impeach Homeland Security chief

U.S. Rep. Mike Gallagher says he won't run for a fifth term in Congress. MADISON, Wis. - U.S. Rep. Mike Gallagher, a key Republican Congressman who has spearheaded House pushback against the Chinese government, announced Saturday that he won't run for a fifth term. The announcement comes just days after he angered his fellow Republicans by refusing to impeach Homeland Security Secretary Alejandro Mayorkas. Gallagher wrote in a Wall Street Journal op-ed published after the vote that impeachment wouldn't stop migrants from crossing the border and would set a precedent that could be used against future Republican administrations. Gallagher did not mention the impeachment vote in a statement announcing his retirement, saying only that he doesn't want to grow old in Washington. "The Framers intended citizens to serve in Congress for a season and then return to their private lives," Gallagher said. Gallagher was one of the highest-profile Republicans considering a run for U.S. Senate this year against incumbent Wisconsin Democrat Tammy Baldwin.
