AIPAC—the American Israel Public Affairs Committee—is a bipartisan, non-profit organization that works to strengthen the U.S.-Israel relationship. AIPAC is registered as a domestic lobby and is supported financially by private donations. AIPAC is not a political action committee and it does not rate, endorse or contribute to candidates. The New York Times has described AIPAC as "the most important organization affecting America's relationship with Israel."​
