Controversial Arizona lawman Joe Arpaio says he will cooperate with the Justice Department investigation into whether he used his law enforcement powers to pursue political vendettas, according to Phoenix television station KPHO.

Arpaio, the Maricopa County sheriff, told the station on Saturday, “I look forward to giving (investigators) everything that we have. Everything on all of the investigations, then I’m going to shut this off.”

It’s not clear what Arpaio meant by “shut this off.”

Arpaio’s statement comes two weeks after it was reported that a federal grand jury had been convened to investigate Arpaio’s actions.

Talking Points Memo reported that the grand jury met last week for the first time in connection with the Justice Department probe. Numerous local officials, judges, and others have said that Arpaio targeted them for investigations after they crossed him. The Phoenix television station said the grand jury has already heard testimony from County Manager David Smith, Deputy County Manager Sandi Wilson and MCSO Chief of Business Operations Loretta Barkall.

Arpaio has sent mixed signals about his approach to the inquiry. He initially said he’d cooperate, but then, according to TPM, he hired a former Bush DOJ lawyer who has filed a series of what some call frivolous complaints, which appear designed to throw sand in the gears of the probe. His latest statement to KPHO indicates he may have decided to cooperate.

Arpaio has gained notoriety for ordering his deputies to descend on Latino neighborhoods to arrest illegal immigrants. His deputies have arrested thousands of undocumented aliens during these roundups.
