PHOENIX — Joe Arpaio, the sheriff of Maricopa County, Arizona, briefed GOP contender Rick Santorum on his investigation into President Barack Obama's birth certificate, the controversial law enforcement official told reporters Tuesday.
After a speech to a Republican gathering in Phoenix where Santorum appeared earlier in the day, Arpaio explained he wanted to inform the candidate of his investigation "as a matter of fairness in case he wouldn't want me to support him."
