Rep. Peter King (R-N.Y.) lashed out against Sen. Rand Paul (R-Ky.) for his opposition to the National Security Agency's controversial surveillance programs in a Fox News interview on Sunday.

King ripped into Paul for threatening to sue the Obama administration over the NSA's surveillance policies, saying the agency is "doing exactly what it's supposed to be doing."

“Rand Paul does not know what he’s talking about. And, Rand Paul is really spreading fear among the American people," King said. “To me, he’s either totally uninformed or he’s part of that hate America crowd that I thought left us in the 1960s."

"In any event, he doesn’t deserve to be in the United States Senate for spreading that type of misperception and absolute lies to be honest with you," King continued.

Earlier on Sunday, Paul defended his class-action lawsuit against the NSA in an ABC News interview, saying Americans should challenge the government's access to personal correspondence without a specific warrant.
