Mayor Bloomberg and former Vice President Al Gore were on hand for the kick-off of this year's Tribeca Film Festival. Gore and Bloomberg traded compliments: Gore said that the mayor's congesting pricing initiative was "gutsy" and when asked if presidential candidates were talking about environmental issues, Gore said, "Well, I think Mike is." And the AP reported, "The mayor, standing to Gore's right, turned red and laughed."

In turn, Mayor Bloomberg said, "People talk about Al Gore being a presidential candidate a lot more serious than they joke about me. This guy could be a presidential candidate. He certainly has experience. I’ve always been in favor of the public having more choice. I hope Al Gore enters the race; I think it would be good for the country.”

And Mayor Bloomberg multi-tasked, as he checked his Blackberry during the press op.
