“Irving Moskowitz, Controversial Backer Of Israeli Settlements, Gives $1 Million To Anti-Obama Super PAC.” Moskowitz gave $1 million to America Crossroads, and according to HuffPo:
Now, at age 83, Moskowitz has turned his money on the American political realm in a more prominent fashion than ever before, funding "birther" groups that question the legitimacy of President Barack Obama’s U.S. citizenship and others that stoke fears about the president’s alleged ties to "radical Islam."
What is not exactly clear is whether contributions to “birther” groups is necessarily supported in the story. The only “birther groups” mentioned by HuffPo is (singular) Joseph Farah’s Western Center for Journalism. While there is no question that Farah and his enterprises are a wellspring of birtherism, they also support anti-Muslim activities and right-wing politics in general. I don’t see the evidence that Moskowitz is himself a birther or has donated money specifically to advance birtherism.
