The backlash over an Ohio campaign advertisement attacking Amy Acton, the Democratic nominee for governor, spread beyond the state's borders Thursday, when President Donald Trump posted on social media that Vivek Ramaswamy's ad was "hitting pay dirt" and that Acton was "fair game." Trump's aggressive defense of Ramaswamy practically guarantees that more of his party's candidates will face questions about the issue at a moment when they already risk being dragged down by the president's low popularity.

Here's the latest: Susan Collins uses Troy Jackson's 'shut up' debate line in new ad Maine Republican Sen. Susan Collins is out with a new ad capitalizing on her opponent Troy Jackson's debate comment telling her to "shut up." "Troy has something to say to Maine women. Shut up," the ad's narrator says.

The ad references a comment Jackson made during a debate Oct. 15, when Collins said a person disrupting the event was "obviously one of Troy's supporters." Jackson responded: "Oh, shut up. I don't even know that kid." He added later that he didn't regret the statement and that he had no idea who the person interrupting the debate was.
