WATCH: John Kerry Slams Netanyahu's Judgement

WASHINGTON AP - Secretary of State John Kerry says Israeli Prime Minister Benjamin Netanyahu might be wrong about his opposition to negotiating a deal with Iran to curb its nuclear program.

Kerry told the House Foreign Affairs Committee Wednesday he didn't want to comment on Netanyahu's upcoming speech to Congress next week. The Israeli leader is expected to argue that Tehran is not negotiating in good faith and that despite its claims to the contrary, it wants to develop a nuclear weapon.

Kerry answered Rep. Gerald Connelly's line of questioning asking for Kerry to comment on Netanyahu's criticism of a potential deal with Iran by questioning Netanyahu's judgement on past issues. "Let me say this. The prime minister, as you recall, was profoundly forward leaning and outspoken about the importance of invading Iraq under George W. Bush, and we all know what happened with that decision."

Political commentators immediately took aim at Kerry's statement, as Kerry himself, then a U.S. Senator, voted for the Authorization for Use of Military Force Against Iraq Resolution of 2002, which gave President Bush legal authorization to attack Iraq.

Kerry also noted that Netanyahu earlier called an interim agreement with Iran as the "deal of the century" for Tehran, but now supports the first-step agreement that the U.S. says rolled back Iran's program while talks ensued.

Kerry says Netanyahu "may have a judgment that just may not be correct here."
