The National Rifle Association is airing a new television advertisement in support of Sen. Kelly Ayotte (R-N.H.) as she faces criticism in at least two other ads on her position on new proposed gun laws.

"Kelly Ayotte voted for a bipartisan plan to make background checks more effective ... to reform our broken mental health system ... for more resources to prosecute criminals who use guns. Kelly Ayotte stands with prosecutors and police for New Hampshire values," the ad's announcer says.
