In late April, the board issued an administrative subpoena to the Maricopa County Sheriff's Office requesting financial records for their RICO, Jail Enhancement Funds and other bank account information.

Officials said the subpoena was issued after Arpaio did not produce the requested information. The board could decide to open up contempt hearings against the sheriff and MCSO.

Sheriff Joe Arpaio says he has decided not to run for Arizona governor.

"Right now, we are standing in the cross-hairs of history in this state and as sheriff of the most populous county in Arizona, there is much work yet to do," he said in a statement.

To leave this office open to appointment by the Maricopa County Board of Supervisors of an interim sheriff may very well put us on a path that would be extremely displeasing to the voters of this county," he said.
