David Costabile
Played by David Costabile

Bobby Axelrod's right hand man is the COO of Axe Capital, Mike "Wags" Wagner. Wags is a patrician WASP who still has to work for a living, and no one has ever kissed ass with more aplomb. But he truly does have Bobby's back, for which his boss rewards him handsomely.

In an April 2013 article about television for Wired, Jordan Crucchiola called actor David Costabile "a performer who inhabits his characters so perfectly as to consistently be a fan favorite."
Costabile's work includes memorable parts in some of the most innovative shows in recent years. In the third and fourth seasons of Vince Gilligan's BREAKING BAD he played Walt's lab assistant Gale Boetticher. On FLIGHT OF THE CONCHORDS Costabile played Doug, Mel's long-suffering husband, and on SUITS as Daniel Hardman, the heavy who fought for control of law firm Pearson Hardman. Costabile's credits also include the final season of David Simon's THE WIRE in which he portrayed the managing editor of a struggling Baltimore Sun, and DAMAGES where he played killer Detective Rick Messer.
Costabile most recently co-starred as a cult leader in the event series DIG and as Simon Boyd, an internal affairs investigator whose murder case begins to go cold on LOW WINTER SUN. He also guest starred on numerous series, including THE OFFICE, THE BLACKLIST, and THE GOOD WIFE.
On film, Costabile memorably portrayed Republican abolitionist James Ashley for Steven Spielberg in LINCOLN, written by Tony Kushner. In 2016, Paramount Pictures will release Michael Bay's 13 HOURS: THE SECRET SOLDIERS OF BENGHAZI, in which Costabile plays the CIA Chief in Libya. His motion picture credits also include Steven Soderbergh's SIDE EFFECTS, RUNNER RUNNER, directed by Brad Furman, and SOLITARY MAN, directed by Brian Koppelman and David Levien, amongst others.
Prior to LINCOLN, Costabile first collaborated with Tony Kushner on the Tony and Drama Desk award wining musical CAROLINE, OR CHANGE co-written by Jeanine Tesori. Costabile performed in the original Shakespeare Festival/Public Theatre production and its Broadway transfer. His Broadway credits also include the Tony Award-winning TITANIC, as well as TRANSLATIONS and THE TEMPEST. Off-Broadway, he has worked at the New York Shakespeare Festival/Public Theatre in  THE TWO GENTLEMEN OF VERONA, HENRY V, and TROILUS AND CRESSIDA. Other Off-Broadway credits include THE (CURIOUS CASE OF THE) WATSON INTELLIGENCE at Playwrights Horizons, MR. MARMALADE at the Roundabout Theatre Co., CARNIVAL and CAN-CAN at the Encores! Series at New York City Center, and THE WINTER'S TALE at Classic Stage Company. THE NEW BOZENA, an original work Costabile co-created, played off-Broadway at the Cherry Lane Theatre before touring nationally.
Costabile was born in Washington, D.C., graduated from Tufts University and received his MFA in Acting from New York University's Tisch School of the Arts in 1998.
