American Jewish billionaire Irving Moskowitz, a financial backer of the pro-settlement movement, has donated $1 million to a conservative super PAC.
Moskowitz's donation to American Crossroads, which is connected to Karl Rove, former Republican National Committee Chairman Ed Gillespie and former Mississippi Gov. Haley Barbour, is the gambling magnate's single largest contribution to U.S. politics, Paul Blumenthal reports in the Huffington Post.
The primary mission of the PAC is to unseat President Obama, according to the Blumenthal article.
Moskowitz, 83, has also donated to "birther" groups that question the legitimacy of Obama's US citizenship and to groups that claim Obama has ties to radical Islamic groups.
Moskowitz and his wife, Cherna, have donated millions of dollars to the settlement movement, including buying property in eastern Jerusalem and to Ir David, which runs the historic City of David archeological park in eastern Jerusalem.
