FBI agent warned of terror plans to attack towers

A MINNEAPOLIS FBI supervisor said in a pre-September 11 conversation with headquarters that he wanted to prevent suspiciousstudent pilot Zacarias Moussaoui from flying a plane into the World Trade Center, a congressional investigator testified yesterday.

The supervisor said he had no reason to believe Moussaoui was planning such an attack.

He made the remark in a frustrated attempt to convince headquarters that a special search warrant was needed to search Moussaoui's computer, investigator Eleanor Hill told a House-Senate committee investigating the September 11 attacks.
