Prosecutors in former Sheriff Joe Arpaio's criminal contempt-of-court case are opposing requests to prohibit the testimony of an attorney who once represented him in a racial profiling case.
They urged a judge Thursday to reject arguments by Arpaio and lawyer Tim Casey that Casey's testimony is protected by attorney-client privilege.
Arpaio and Casey want to prevent Casey from testifying at the lawman's April 25 trial on a criminal contempt charge.
Arpaio faces the charge for defying a court order in the profiling case requiring him to stop his immigration patrols.
He acknowledged prolonging his patrols, but insists his disobedience wasn't intentional.
Casey defended Arpaio in the case for nearly six years before bowing out in November 2014.
Casey was forced to testify at an earlier contempt hearing for Arpaio.
