National Rifle Association head Wayne LaPierre said Sunday that New York Mayor Michael Bloomberg (I) is trying to "buy America" by spending millions of his personal fortune to urge key senators to vote for gun control.

"He can't spend enough of his $27 billion to try to impose his will on the American public," LaPierre said on NBC's "Meet the Press." "They don't want him in their restaurants, they don't want him in their homes, they don't want him telling what food to eat. They sure don't want him telling what self-defense firearms to own. He can't buy America."

Bloomberg said earlier on the show that he will spend $12 million of his vast personal fortune -- he's been ranked among the 10 richest Americans by Forbes -- on ads targeting key senators in the gun control debate. The ads were reported Saturday by the New York Times.

LaPierre said Bloomberg is making irresponsible claims about gun owners and the NRA.

"It's insane the stuff he says," LaPierre said.
