From CBS News' John Bentley:
For the first time since he became the presumptive Republican nominee, President Bush will hold a fundraiser for John McCain today. Originally scheduled for the Phoenix Convention Center, the event was moved to a private home in Phoenix. Differing reasons have been given for moving the fundraiser – the McCain camp says they have a closed fundraiser policy and in order to keep in line with White House protocol, which allows press coverage of fundraisers in public places, they decided to move it to a private home. But the Phoenix Business Journal reported that tickets were not selling well and there were concerns about large numbers of protestors disrupting the event.
There are no plans for the two to talk to the press, or to even be seen together for more than a few moments when the president departs on Air Force One, according to the Wall Street Journal.
McCain also has two other fundraisers scheduled for today in Colorado, as well as a speech at the University of Denver.
