Einhorn served as Schatz’s senior counsel for technology and communications policy where he focused on issues of data privacy and security, antitrust and intellectual property matters, according to a press release from Schatz’s office announcing the hire. Prior to working for Schatz, Einhorn worked in government affairs for more than a decade at Windstream Communications, a telecommunications company, according to his LinkedIn account.
