That needs a link.
On recollection, Billy Ayers and Barack Obama served together on the board of a boondoggle charity, the Chicago Annenberg Challenge, funded by the Annenberg Foundation, which also has funded FactCheck.org. Anybody have any evidence of direct involvement in FactCheck by Ayers or Obama?

Maybe there are no clear ties at this time, maybe not.
