Israeli Prime Minister Benjamin Netanyahu is addressing the American Israel Public Affairs Committee (AIPAC) meeting on Monday, a day before his controversial speech to Congress. But the Obama administration isn't giving Netanyahu an empty stage to make his case against a prospective nuclear deal with Iran. White House National Security Adviser Susan Rice and U.N. Ambassador Samantha Power will make the case for the deal at AIPAC, and Obama will likely discuss the Iran negotiations in an interview scheduled with Reuters on Monday afternoon.
