Marcus Walker is the Director of Communications at The White House. Prior to his gig at the Oval he was the newest gladiator at Olivia Pope & Associates. Starting out as a neighborhood activist, Marcus has his own way of handling things and will fight for his beliefs as long as his hands are able to hold a megaphone. He can easily be seen as the moral compass for the OPA gang. But don't be fooled, in true Scandal fashion, he made headlines of his own when he admitted to having an affair with the mayor's wife. What sets him apart? He's a champion for the truth.
