The long awaited Memorial to Flight 93 is getting some help from past and present political leaders.  Former Presidents George W Bush and Bill Clinton will join Speaker of the House John Boehner tomorrow night.  They will headline a fundraiser at the "Newseum" in Washington.  Money will go toward completing a Memorial underway in Shanksville.  That's the site where the final plane crashed on September 11^th when passengers confronted terrorists.
