The Department of Justice is suing Joe Arpaio, Sheriff of Maricopa County, Arizona, for failing to cooperate with its investigate into alleged discrimination against Hispanics by Arpaio and his department.

Arpaio forced the DOJ's hand by publicly refusing to provide documents requested for the investigation. It seems obvious to me that it would not have come to this if Bush or McCain were president.
Arpaio keeps finding ways of being more extreme - even arresting a Republican county Supervisor who disagreed with some of Arpaio's extreme tactics.
This is one of the best things to come out of the Obama Administration, I think.
