Sheriff Arpaio had another press conference on March 31 about the results of his "Cold Case Posse" (led by Mike Zullo) in regard to Barack Obama's birth certificate.
The link below is to the video of the March 31 press conference. Zullo's entrance and opening remarks start at 41:00. The actual details start at 47:00
Zullo not only presents his own, very convincing evidence, but he also debunks the counterarguments made by the left and by Bill O'Reilly. Worth watching Zullo's entire presentation.
