(CNN) -- Hours after a judge told embattled Detroit Mayor Kwame Kilpatrick he could remove his electronic tether and travel to the Democratic National Convention, another judge ordered him to put it back on and restricted him to three Michigan counties.
Calls for the resignation of Detroit, Michigan, Mayor Kwame Kilpatrick continue to mount.
Wayne County Circuit Court Judge Leonard Townsend, who was handling the mayor's arraignment Thursday for perjury and other charges, granted permission for Kilpatrick to travel to Denver, Colorado, later this month for the Democratic National Convention.
He also ordered an electronic tether to be removed from Kilpatrick's ankle.
However, Michigan 36th District Judge Ronald Giles, who is overseeing two assault charges against Kilpatrick, later Thursday signed an order clarifying the conditions of the mayor's release in that case.
According to the order, Kilpatrick must remain on the electronic tether or other GPS device, and stay within Wayne, Oakland and Macomb counties, Giles said. He is also not allowed contact with three witnesses in the case.
Magistrate Renee McDufee initially set these conditions of the mayor's release on August 8, at his arraignment. Giles said those conditions carried through his court.
The conditions do not include an exception to attend the Democratic convention later this month.
"The mayor's attorneys did not object to this [Thursday order]," said Rusty Hills, a spokesman for the Michigan attorney general's office, which is prosecuting the case.
A preliminary hearing for the assault charges will be held Friday morning, Hills said.
The charges, filed last week, stem from a July 24 incident that took place as officers attempted to serve a friend of Kilpatrick with a subpoena.
Kilpatrick has been embroiled in a public scandal since January, when the Detroit Free Press reported he had exchanged romantic text messages with his former chief of staff, Christine Beatty, indicating the two were involved in an affair.
At a police whistle-blower trial in 2007, the pair, under oath, denied any romantic involvement.
Both were charged with multiple counts of conspiracy, perjury, misconduct in office and obstruction of justice.
Giles ordered Kilpatrick jailed for a night earlier this month after learning the mayor had traveled to Canada on Detroit business without notifying the court in advance as required under terms of his bond for the perjury case.
Kilpatrick has remained defiant, and rejected calls for his resignation from critics, including the president of the Detroit City Council.
Meanwhile, two powerful Michigan voices joined the growing chorus of people calling for Kilpatrick to resign.
U.S. Rep. John Dingell, the state's senior congressman, and the Michigan Chronicle, an African-American newspaper, have urged Kilpatrick to step down.
Dingell called the situation sad.
"The matter with Mayor Kilpatrick is dragging down the business and the hopes of the city," Dingell said in a statement advising Kilpatrick to step down.
The Chronicle, which had supported Kilpatrick in the past, published an editorial titled "Mayor Kwame Kilpatrick must leave office."
"We strongly urge the mayor to step aside and address his problems," the editorial said. "His issues are holding the city hostage. Detroit's future is bigger than the mayor."
The two are part of a growing number of critics who have publicly asked for Kilpatrick to quit, including the president of the Detroit City Council.
