And sources tell TIME that Lieberman has named Michael Lewan, who was his administrative assistant from 1989-93, to be his campaign chief-of-staff. Lewan, 49, will take an unpaid leave-of-absence from his Washington lobbying shop, where he has represented several life insurance industry clients, Oracle Corp., BellSouth and others. Lewan will travel with Lieberman, while Tom Nides, the Gore campaign staffer who had been detailed to assist Lieberman, will remain in Nashville to coordinate the activities of the two candidates. Meanwhile Sherry Brown, the longtime head of Lieberman's Connecticut office, will move to Washington to head up Lieberman-connected Democratic fundraising efforts.
