PHOENIX (AP) — An audio recording has surfaced of an Arizona sheriff playing his refusal to cooperate in a racial profiling investigation for laughs at a fundraiser for an anti-illegal immigration group in Texas.

Maricopa County Sheriff Joe Arpaio displayed contempt toward federal authorities who at the time were — and are still — investigating him on two fronts.

His comments in the 2009 audio recording came as the U.S. Justice Department had already launched a civil rights probe of his trademark immigration patrols and the FBI was already examining abuse-of-power allegations for the sheriff's investigations of political foes.

Arpaio, the self-proclaimed "America's toughest sheriff," boasted in the September 2009 speech in Houston that he arrested hundreds of illegal immigrants after politicians and federal investigators started to pick apart his patrols.
