The National Rifle Association is spending another $6.5 million on ads bolstering Republican presidential nominee Donald Trump.

The new ad buy is the largest yet and will run in battleground states Ohio, Nevada, North Carolina, Pennsylvania, and Virginia, Politico reports. It features the story of a Kentucky woman, Kristi McMains, 26, who was able to use a gun she carried in her purse to fight off a knife-wielding attacker in a parking garage.

"A man attacked me in a parking garage, tried to stab me with an 8-inch knife," McMains says in the ad. "But I carry a pistol. I fight back."

"That’s why I’m still here."

The ad draws a black and white distinction between Hillary Clinton and Trump when it comes to gun rights and gun control.

"Every woman has a right to defend herself with a gun if she chooses," McMains says. "Hillary Clinton disagrees with that. Don’t let politicians take away your right to own a gun. Donald Trump supports my right to own a gun."

The ad buy will attempt to draw attention to the gun debate, which has taken a backseat to many other issues in the presidential election. Though Clinton and Trump hold starkly different positions on gun issues, the campaigns have largely ignored guns on the campaign trail and in the debates up to this point. The NRA has tried to keep the issue in the spotlight since strongly endorsing Trump, despite his past support for gun control measures.

McMains’ entrance into the gun rights movement was driven, in large part, by her friendship with rape-survivor and fellow activist Kimberly Corban. McMains said she decided to start carrying her gun after seeing Corban tell her story to President Obama during a CNN town hall in January. The two met and became friends at the NRA’s Annual Meeting in May.

The ad ends with McMains asking people to vote for Trump.

"Defend your rights," she says. "Vote Donald Trump for president."
