Kilpatrick was scheduled to be arraigned Friday on charges of assaulting two Wayne County investigators. It's one of two criminal cases against the mayor, who denies shoving the pair while they tried to deliver a subpoena to a friend.

Kilpatrick is barred from traveling outside the metro Detroit area. Those bond restrictions likely will be discussed at the arraignment. The mayor also is required to wear an electronic tether to monitor his whereabouts.

In Kilpatrick's other criminal case, involving allegations of perjury and obstruction of justice, a judge has said he can go to Denver for the convention.
