Ashley Keller is a pioneer in getting corporations to pay up. As an attorney and founding partner of the firm Keller Postman, he recently pioneered an influential mass arbitration strategy, argued a case against Monsanto at the Supreme Court, and is fighting Google on behalf of several states in a major ad tech antitrust case. Keller is also an avowed conservative and originalist. For him, there’s no contradiction between fighting for conservative principles and antitrust enforcement.

Today on the show, Matt Stoller and David Dayen talk to Keller about the conservative case for antitrust, the dangers of corporate power, and his legal worldview. They go into detail on his current work against Google and the programmatic ad market, his recent appearance at the Supreme Court, his take on the Live Nation Ticketmaster case, the role of plaintiff’s lawyers in the legal exosystem, and get into some big-picture legal questions about antitrust enforcement from an originalist perspective.
