Joe Arpaio's chief deputy David Hendershott gave a deposition in the racial profiling lawsuit brought by the American Civil Liberties Union and, per this, said among other things:

"I believe also that it has become clear that you, (attorney) Bill Strauss, (Phoenix Mayor) Phil Gordon, members of the Anti Defamation League . . . have a political agenda that you are trying to push with this... Your members and others have worked in concert with the Department of Justice in producing what amounts to large amounts of enflamed media that we have learned . . . is basically the only basis that the Department of Justice sent us this letter... ...Racial profiling is a state of mind... We can only deal with facts... I believe that the Obama administration has a political agenda that involves some form of either amnesty or something that does not comport or is not convenient to the current law... The high-profile nature of the sheriff has become a concern, and therefore we are dealing with this."

While there's certainly the possibility that those listed aren't loosely coordinating their actions and it would be difficult to find proof of them doing that, those groups listed are part of a general network that supports illegal immigration in various ways.

Note that the lawyer who took the deposition, David Bodney, is also a lawyer for the Arizona Republic.
