Bank One Corp.'s First USA credit card division announced Tuesday that its president, Randy L. Christofferson, has resigned.
The move came less than three months after Bank One transferred its $30 billion consumer lending portfolio to First USA. Mr. Christofferson held responsibility for managing the portfolio with Richard W. Vague, First USA's chairman and chief executive officer. For now, Mr. Vague will take over Mr. Christofferson's responsibilities.
