A Senate Republican is standing up for a GOP colleague in his contentious reelection bid, despite opposition from President Trump. Sen. Joni Ernst (R-Iowa) will speak at a Phoenix fundraiser for Sen. Jeff Flake (R-Ariz.) in support of the senator's reelection campaign against a pro-Trump challenger, according to azcentral.com. Ernst will appear at a Young Republicans meet-and-greet event on Sept. 7, followed by a "Women for Flake" fundraiser the next day, Flake's campaign told the paper.
