According to this, all Maricopa County Sheriff's deputies will receive private training "on the authority of local law enforcement to enforce federal immigration law". Previously, just 100 of their deputies had received training from the Department of Homeland Security, but the DHS dropped that last year. Law professor and candidate for Attorney General of Kansas Kris Kobach will be providing the training (with his costs self-funded or paid by an unknown group), causing a meltdown among the supporters of illegal activity:

Alessandra Soler Meetze, executive director of the American Civil Liberties Union of Arizona, said Kobach is not qualified to offer the training... "He's a private individual, he's not a law-enforcement officer, he's not certified to represent the federal government or to train law enforcement officers on how to enforce immigration law," she said.

UPDATE: Bill Straus of the Anti Defamation League repeats the same nonsensical talking point here:

"I do not know what qualifies him to train law enforcement offices, he is not one of them."

Kobach explains:

"I am providing some legal expertise what the rules are according to the courts of the United States on questioning individuals," said Kobach via satellite Wednesday... The Sheriff's office will pay Kobach for his expertise from a fund of money seized from criminals. Sheriff Joe says the professor was only in Phoenix very briefly and made a video they'll use for training.
