Israel's prime minister says he is delivering a contentious speech to the U.S. Congress out of a "deep and genuine concern" for Israel's security. Benjamin Netanyahu said he will "do everything" to protect Israel. He spoke Sunday just before boarding a flight to Washington. Netanyahu plans to address Congress about a potential agreement between Iran and six world powers - including the United States - which he fears could allow Tehran to get a nuclear weapon. The speech planned for Tuesday has set off an uproar. Netanyahu angered the White House and Democrats by accepting the invitation from Republicans, who did not consult with the administration in advance. Netanyahu meanwhile has faced a wave of criticism for the address in Israel, where he seeks re-election later this month.
