The National Rifle Association is airing a new television ad in four battleground states urging voters to defeat President Obama.
The pro-gun-rights group is spending $1.3 million to air the ad in Florida, Ohio, Virginia and Wisconsin. A spokesman said the group will be on the air with ads through election day November 6.
The NRA ad suggests Obama is "attacking our Second Amendment rights" and says a vote against the Democrat would help "defend freedom."
The group has endorsed Republican Mitt Romney, even though Romney signed a ban on assault weapons as Massachusetts governor.
Obama hasn't pushed gun control measures as president and has signed laws letting people carry concealed weapons in national parks and in checked bags on Amtrak trains.
