More than one year after he stopped working with the Hillary Clinton presidential campaign, Mark Penn has finally received full payment for his services.

Bloomberg reports that Clinton has “erased most of her presidential campaign debt” and that “The last outstanding bill was $1.5 million to former chief strategist Mark Penn.” The check went to Penn’s firm, Penn, Schoen & Berland Associates, a subsidiary of WPP (WPPGY). Penn also serves as CEO of Burson-Marsteller.
