F.B.I. agents executed search warrants Friday in Minneapolis and Chicago in connection to an investigation of support of terror organizations.

The searches in Minneapolis took place early in the morning at the homes of people who have helped organize demonstrations against the war in Iraq and protests held two years ago during the Republican National Convention in St. Paul.

“It is rather patently political,” said Ted Dooley, a lawyer who represents Mick Kelly, a food service worker at the University of Minnesota and one of those whose homes was searched. “My client denies any wrongdoing.”

Steve Warfield, a spokesman for the Federal Bureau of Investigation in Minneapolis, said the agents executed six warrants in Minneapolis and two in Chicago.
