A spokesman for Israeli opposition leader Isaac Herzog says the center-left lawmaker will travel to Washington to discuss Israel's concerns over the Iranian nuclear deal.

There is widespread objection in Israel to the deal. It was also a heavy blow to Prime Minister Benjamin Netanyahu who spent years trying to prevent it.

Herzog's spokesman Ofer Newman told The Associated Press on Wednesday that in Washington, the lawmaker will "explain what the problem is with the agreement" and discuss its security implications.

Herzog has blamed Netanyahu for the nuclear deal but in a meeting with the prime minister late Tuesday, he enlisted "to do everything for the security of Israel," according to a statement from Netanyahu's office.

Newman didn't elaborate on the timing of Herzog's trip or who he will meet.
