McDonough will recur as Sean Cahill, an SEC investigator tasked by Eric Woodall (guest star Zeljko Ivanek) to root out any wrongdoings at Pearson Specter. Described as a “bulldog” of a man, Cahill is ready and willing to fight anyone to achieve his goals.
He should prove to be an entertaining and dangerous foe for Harvey (Gabriel Macht).
Most recently seen on a Super Bowl commercial for Cadillac, McDonough has a long list of TV credits, including “Justified,” “Desperate Housewives” and “Mob City.”
The premiere of “Suits” Season 4 will air Wednesday, June 11 at 9 p.m. ET/PT on USA.
