CBNNews.com - NEW YORK CITY- Former Democratic presidential candidate Senator Hillary Clinton canceled her appearance at an anti-Iran rally slated for September 22 in front of the U.N. building.

The rally, aimed at protesting Iranian President Mahmoud Ahmadinejad's call for Israel's destruction and his invitation to speak again at the U.N., is being organized by several American Jewish organizations.

Clinton canceled her appearance after learning that Republican vice presidential candidate, Governor Sarah Palin, had been invited, though her attendance has not yet been confirmed.

Clinton aides were irate.

"Her [Palin's] attendance was news to us, and this was never billed to us as a partisan political event," said the senator's spokesman Philippe Reines.

"Senator Clinton, therefore, will not be attending," he said.

Sponsors of the rally include the Conference of Presidents of Major American Jewish Organizations, the National Coalition to Stop Iran Now, United Jewish Communities, and the Jewish Community Relations Council of New York.
