The Latest: Former Arpaio underling testifies against him

Another member of former Sheriff Joe Arpaio’s immigrant enforcement squad has testified against his old boss.

Sgt. Michael Trowbridge testified Wednesday that he witnessed a tense exchange in which a colleague complained to Arpaio that a command the sheriff had issued would have violated a judge’s order.

Arpaio is charged with misdemeanor contempt of court for disobeying a federal judge’s order to end his patrols that rounded up immigrants suspected of being in the U.S. illegally.

Trowbridge says he served in Arpaio’s immigrant enforcement squad from March 2011 until March 2013 , but was aware of the December 2011 order when it came out.

Trowbridge says no one explained the order in any great detail to him or other officers, but he realizes the policy of turning immigrants over to the feds violated the injunction.
