New Jersey Gov. Chris Christie is labeling “reprehensible” the National Rifle Association ad that brought President Barack Obama’s daughters into the gun-control debate.

The NRA ad accused the president of being a hypocrite for allowing his daughters to be protected by armed Secret Service agents but not embracing armed guards for schools.

The Republican governor and father of four said at a briefing Thursday in Trenton that the children of public figures should be off-limits to political attacks.
