This week Dahlia Lithwick calls on white-collar-crime specialist Jennifer Taub to follow the money in the Mueller investigation. She also speaks with  Bob Bauer, a former White House counsel under President Barack Obama, about the relationship between presidents and their lawyers, and between this president and his lawyers. Bauer discusses when professional duty can stray into enabling, a question facing Trump’s personal and institutional lawyers as cases involving the president accumulate.
