The American Israel Public Affairs Committee (AIPAC /'e?pæk/ AY-pak) is a lobbying group that advocates pro-Israel policies to the Congress and Executive Branch of the United States. The current President of AIPAC is Lillian Pinkus. One of several pro-Israel lobbying organizations in the U.S., AIPAC states that it has more than 100,000 members, seventeen regional offices, and "a vast pool of donors." California Congressman Brad Sherman has called AIPAC "the single most important organization in promoting the U.S.-Israel alliance." In addition, the organization has been called one of the most powerful lobbying groups in the United States. The group does not raise funds for political candidates itself, but its members raise money for candidates through PACs AIPAC helped establish and by other means. Its critics have stated it acts as an agent of the Israeli government with a "stranglehold" on the United States Congress with its power and influence. The group has been accused of being strongly allied with the Likud party of Israel, and the Republican Party in the US, but an AIPAC spokesman has called this a "malicious mischaracterization." The Washington Post described the perceived differences between AIPAC and J Street: "While both groups call themselves bipartisan, AIPAC has won support from an overwhelming majority of Republican Jews, while J Street is presenting itself as an alternative for Democrats who have grown uncomfortable with both Netanyahu’s policies and the conservatives’ flocking to AIPAC."
