NRA executive director Chris Cox tonight fired back at the White House’s defense of a proposed ammunition ban.

The ATF has proposed banning an extremely popular type of ammunition used by more than 4 million gun owners in the United States. Gun groups challenged the proposal, but the White House defended it, saying that these bullets pose a special risk to law enforcement.

Cox said that President Barack Obama wanted to ban the AR-15, but couldn’t get that through Congress. Now, he’s trying to ban the ammunition for the AR-15, Cox said.

“This president hates guns, he always has,” Cox said. “He doesn’t care for the Constitution, he says he’s got his cellphone and his pen and he’s gonna ignore it. Well, we can’t do much about his hatred, but we can do something about trying to dismantle the Second Amendment.”

Cox said that not one officer has died as a result of vest penetration from one of these rounds in the last 30 years since ATF exempted the ammo.

“This is a solution not to a problem, it’s a solution to Barack Obama’s gun control problem,” Cox said.

Cox vowed that the NRA will fight this proposal every step of the way. He added that the NRA will work to elect a president “who does something other than disrespect this freedom.”
