PHOENIX (AP) - Former Sheriff Joe Arpaio has asked the U.S. Supreme Court to reverse the appointment of a special prosecutor to defend a ruling by the judge who refused to erase Arpaio's record after President Donald Trump pardoned his contempt of court conviction.
The former sheriff made his filing Wednesday at the nation's highest court.
The special prosecutor's appointment came after the U.S. Justice Department refused to defend the ruling that dismissed his case after Arpaio was pardoned but refused to expunge his record.
Arpaio was convicted of contempt for his disobedience of a court order to stop traffic patrols that targeted immigrants.
The pardon spared Arpaio a possible jail sentence.
Justice Department lawyers won the conviction. But after the pardon, the department sided with Arpaio, arguing the conviction should be expunged.
