Cook takes the title of VP of digital engagement in New York, departing a Washington-based managing director slot at CLS Strategies. He was Pennsylvania digital director for the Obama-Biden re-election in 2012 and handled digital strategy for former Sen. Russ Feingold (D-Wisc.).

BR principal and co-founder Valerie Berlin said the addition of Cook to lead a digital operation lets the firm be a "one-stop-shop" for social media, multimedia and online advertising.

The firm, which made a splash aiding the election of Bill de Blasio as mayor of New York last fall, counts 55 staffers with additional outposts in Washington and Los Angeles. It also advised Cornell University's successful bid for a tech campus in Manhattan and the national fast-food worker strikes in December.
