Since Jan. 10, Kilpatrick has been barred from traveling to the Dallas area where his wife and three sons live. He's staying at the Detroit home of his mother, former U.S. Rep. Carolyn Cheeks Kilpatrick, while on trial on corruption charges.
Kilpatrick didn't comment at the courthouse, but Flood expressed concern. He said jurors might hear about the weekend in jail and draw an unfavorable impression, even though they've been told to avoid news reports during the trial.
"If a juror hears that, you don't want it in the back of their mind when they decide the case," Flood said.
Kilpatrick is charged with a series of crimes related to an alleged scheme to pocket hundreds of thousands of dollars through racketeering and extortion. The government says many of his targets were contractors who did business with the city and were desperate to keep it. His father, Bernard, and a close friend, Bobby Ferguson, also are on trial.
An Internal Revenue Service agent testified Friday that Kilpatrick should owe $200,000 in back taxes tied to unreported income.
Kilpatrick, a Democrat, was elected Detroit mayor in 2001. He resigned in 2008 and pleaded guilty to obstructing justice by lying in a civil case about having sex with an aide. He subsequently served 14 months in prison for violating his probation in that case.
