House Budget Chairman Paul Ryan (R-WI) criticized the National Rifle Association on Wednesday over an advertisement that targeted President Barack Obama's daughters, according to the Washington Post.

"Our kids are out of bounds,” Ryan told reporters. “The Obama campaign [and] the national media respected that of my family, and we’re grateful for that. Our kids ought to be out of bounds."

The NRA ad, released last week, attacked Obama as an "elitist hypocrite" because his daughters have armed guards protecting their school. The NRA has called for armed guards to be placed in every school to prevent mass shootings, a proposal the President has mostly dismissed.

It was soon revealed the ad was factually incorrect. Sidwell Friends, where Obama's daughters attend school, does not have any armed guards.

Ryan is not the first prominent Republican to publicly criticize the ad. Last week, New Jersey Gov. Chris Christie described the ad as "reprehensible."
