CHARLESTON, W.Va. -- The National Rifle Association is targeting U.S. Sen. Joe Manchin after years of endorsing the West Virginia Democrat.
Manchin has continued to push to broaden background checks to include firearms sold online or at gun shows.
The NRA says it launched a TV ad Wednesday urging state residents to call Manchin over the measure.
Manchin says the NRA is more concerned about political power than gun rights and safety.
The ad links Manchin to President Barack Obama, who is unpopular in the state, and New York City Mayor Michael Bloomberg.
The TV spot contrasts Manchin's proposal with his 2010 campaign ad, in which Manchin shoots a rifle while touting his support of Second Amendment rights.
The NRA says it will spend $100,000 to air its ad over the next two weeks.
