PHOENIX -- A fundraiser for presumptive Republican presidential nominee John McCain at the Phoenix Convention Center has been canceled.

Convention Center spokeswoman Alexandria Van Haren says the event scheduled for Tuesday evening is no longer being held at the downtown location and that the fundraiser will be held at an undisclosed site.

Calls to the McCain campaign, which had listed the Convention Center event on its Web site, weren't immediately returned Friday evening.

President Bush, however, is still scheduled to attend a McCain fundraiser on Tuesday at a private home in Arizona.

Van Haren says she didn't know the reason why the Convention Center event was canceled.

Dana Kennedy, a spokeswoman for the Arizona AFL-CIO, says McCain supporters would have been greeted by hundreds of protesters outside the Convention Center.
