Center for American Progress, group tied to Obama, under fire from Israel advocates The Center for American Progress, a liberal think tank closely aligned with the White House, is embroiled in a dispute with several major Jewish organizations over statements on Israel and charges that some center staffers have used anti-Semitic language to attack pro-Israel Americans. The controversy reflects growing divisions among important allies of President Obama over Middle East policy that could complicate the president's reelection outreach to some Jewish voters, just as he is seeking to assure them of his commitment to Israel's security amid fears of an Iran nuclear threat. Among the points of contention are several Twitter posts by one CAP writer on his personal account referring to "Israel-firsters." Some experts say the phrase has its roots in the anti-Semitic charge that American Jews are more loyal to a foreign country. In another case, a second staffer described a U.S. senator as showing more fealty to the prime U.S. pro-Israel lobby, the American Israel Public Affairs Committee, than to his own constituents, replacing a standard identifier of party affiliation and state with "R-AIPAC" on his personal Twitter account. The first writer has since left the staff. Critics are also pointing to writings on the CAP Web site, where staffers have suggested the pro-Israel lobby is pushing the U.S. toward war with Iran and likened Israel's treatment of Palestinians in Gaza to the policies of the segregated American South. Those statements, among others, have gained notice largely because of CAP's influential role in Obama's Washington. Founded and chaired by John Podesta, a onetime chief of staff in the Clinton White House, the center is an idea generator for the administration and a source for many of its top officials. The executive who headed the arm overseeing the CAP bloggers, Jennifer Palmieri, recently became a top communications official in the White House, and Podesta is now a part-time adviser to the State Department. Several major Jewish groups have demanded corrective action by the think tank and asked for answers from friends in the White House. "The language is corrosive and unacceptable," said Rabbi Abraham Cooper, associate director of the Simon Wiesenthal Center. He added that the blog posts and tweets from CAP staffers "are the responsibility of the adults who run the place, not only the kids who play." Cooper conveyed his concerns about CAP during a private White House meeting last week with Obama's newly hired Jewish community liaison. The White House official, Jarrod Bernstein, told Cooper that the situation at CAP was "troubling," adding "that is not this administration." A White House spokesman, Matt Lehrich, declined to comment on CAP. He said Obama "has repeatedly reiterated America's unshakable commitment to Israel's security and stood up against attempts to single out Israel in international forums." He added that the administration has "ratcheted up unprecedented pressure on Iran." Abraham Foxman, national director of the Anti-Defamation League, said some of the statements from CAP staffers "are anti-Semitic and borderline anti-Semitic."
