Mahlon Clift 2 First up on the stand Tuesday morning was longtime friend of Kwame Kilpatrick, a former buddy from his college years, Mahlon Clift.

Local 4 Defenders cameras rolled as Clift left court Tuesday after delivering surprising testimony in Kilpatrick's federal trial.

Once, Clift says, he was visited by Ferguson at his hotel room at the Antheneum Hotel Suite in Greektown, Detroit. During that meeting, Clift testified, Ferguson delivered a gift bag filled with $90,000 in cash. Clift says Ferguson made it known the money was meant for "Black," which is Kwame Kilpatrick's nickname among certain friends.
