Maricopa County Sheriff Joe Arpaio looks on in the foreground as a copy of President Obama's selective service card is displayed during a news conference Thursday, March 1, 2012, in Phoenix. Arpaio has unveiled preliminary results of an investigation, conducted by members of his volunteer cold-case posse, into the authenticity of President Barack Obama's birth certificate. Arpaio said the probe revealed that there was probable cause to believe Obama's long-form birth certificate released by the White House in April and the selective service card are forgeries.
