The National Rifle Association is targeting U.S. Sen. Joe Manchin after years of endorsing the West Virginia Democrat.
A TV ad the group planned to launch Wednesday urges state residents to call Manchin over gun control.
Manchin has continued to push to broaden background checks to include firearms sold online or at gun shows. He was not immediately available for comment.
The ad seeks to link Manchin with President Barack Obama and New York City Major Mike Bloomberg. Obama is unpopular in West Virginia.
The new TV spot also invokes the famous campaign ad in which Manchin shots a rifle at Obama environmental legislation. That 2010 ad had cited the NRA’s endorsement of Manchin.
The NRA says it will spend $100,000 to air the ad over the next two weeks.
