A controversial Arizona sheriff says he dares the Rev. Al Sharpton to visit his town to protest policies against inmates and undocumented workers. Some months ago, Sharpton threatened to march on Phoenix unless Maricopa County Sheriff Joe Arpaio resigned. Sharpton has been an outspoken critic of what he says is Arpaio’s penchant for detaining even legal Mexican immigrants and embarrassing and dehumanizing those held in his jail. But in a letter dated June 3, Arpaio shot back at the high-profile civil rights leader. “This is about you making self-serving, grandiose pronouncements, making outrageous statements at meaningless press conferences,” the sheriff writes.

Kwame Kilpatrick’s trip to DNC still in question.

Mayor Kwame Kilpatrick is due in court tomorrow for the fifth time in weeks, where he’ll be arraigned on charges that he assaulted a sheriff’s deputy last month. Kilpatrick also faces criminal charges of perjury for his alleged involvement in a cover-up of a police investigation and his denial under oath that he had an extra-marital affair with his former chief of staff. The denials contradict hundreds of text messages sent between Kilpatrick and Christine Beatty, who also faces perjury charges. Kilpatrick’s next court appearance could determine whether he’s free to travel to next week’s Democratic National Convention and historic nomination of Barack Obama. Last week, Judge Leonard Townsend reversed an order that Kilpatrick wear an ankle tether and be restricted from leaving metro Detroit after a bond violation. But within hours, Kilpatrick was tethered again, due to separate restrictions connected with the assault charge. Townsend shocked prosecutors by openly advocating in court for the mayor to attend the Democratic National Convention, but Kilpatrick has said he doesn’t want to be a distraction. Many critics of the mayor say his association with Obama could cost the presidential candidate votes in November.
