Two Asian-American groups asked Sheriff Joe Arpaio to resign at a Tuesday event hosted by Citizens for a Better Arizona President Randy Parraz and by Maricopa County Supervisor Mary Rose Wilcox.

Parraz and Wilcox long have sought Arpaio's ouster. Last month, Valley Black leaders also implored the sheriff to step down.

Asian Chamber of Commerce Director Madeline Ong-Sakata said Tuesday, "We are joining with our African-American and Hispanic-American brothers and sisters to ask Sheriff Joe Arpaio to resign."

"His obsession with Hispanics, legal or illegal," makes Arpaio "ineffective," she said.

Asian Pacific Community in Action President Doug Hirano said many of his members considered "racial profiling by the Sheriff's Office reminiscent of policies of countries Asian-Americans have fled."

Arpaio responded that Parraz and Wilcox "put this all together" and that "the majority support me in this fight against illegal immigration."
