Hill Harper has joined the cast of the USA Network's drama series Covert Affairs for its 4th season, in a series regular role.

Currently co-starring on CBS' CSI: NY, that show looks to be ending its run, with its season finale airing tonight, and it hasn't been renewed for another season.

The 16-episode Season 4 of Covert Affairs is currently filming in Toronto, and will feature Hill Harper as "an ambitious CIA station chief based in Latin America who is plotting his way into a bigger position back in Washington and seeks Annie and Auggie’s help, but his questionable actions will cause them to doubt his intentions."

Covert Affairs stars Piper Perabo and Christopher Gorham, and centers on a young CIA trainee, Annie Walker, who is sent to work at the Domestic Protection Division (DPD), where she serves as a field agent. August "Auggie" Anderson, a blind tech operative, is Annie's guide in her new life. Annie's cover story is that she works in Acquisitions at the Smithsonian Museum.
