Tad Whitney is a spokesperson at the Department of State whom C.J. Cregg interviewed for a job as Deputy Press Secretary at the White House. He was not hired; instead, C.J. promoted Simon Glazer "from within."
Tad believed C.J. chose another candidate because they had dated five years earlier and Tad ended the relationship after six weeks when he stopped calling her. He confronted her during a concert at the Kennedy Center, threatening to become a problem due to C.J.'s "unprofessional" decision, but C.J. was preoccupied with other matters.
