Patrick Murphy, a former U.S. representative and acting secretary of the Army under President Barack Obama, has left Dilworth Paxson after a short stay to join the cybersecurity and data privacy group at FisherBroyles in Philadelphia.

Murphy made the move after just three months at Dilworth Paxson, drawn to FisherBroyles’ distributed firm model, better compensation and growing cybersecurity and data privacy group, which includes more than two dozen attorneys.
