Rep. Adam Schiff (D-CA) and Denis McDonough, Obama's senior foreign policy adviser, held a conference call with reporters to respond to the remarks made this morning by John McCain to AIPAC.

"There were two questions the senator failed to answer," Schiff said of McCain. "The first is: How would his policy be any different than the president's? The second: If it's no different, and it appears from the substance of his remarks that it really isn't any different, why should anyone expect that he'll have better results than this president has?

"Unfortunately, he continues to cling to a foreign policy that's failed to make the U.S. or Israel safer. ... The only thing that appeared at all new in Senator McCain's remarks was an adoption of a divestment policy and a sanctions approach, which, ironically, has been something Obama has been championing for some time."

"Senator McCain was right about one thing in his speech," McDonough said. "He certainly took great effort and went to great lengths to highlight Democrats and the role that they have played over the course of history of the U.S.-Israel relationship ... But as much as he wants to try to run on the Democratic tradition of a strong foreign policy and strong support for Israel, he is running on a series of policy trends from this administration that have had the opposite impact."

Obama plans to speak at the AIPAC conference Wednesday. He previously spoke at the AIPAC Policy Forum in Chicago in early March.
