Robert Reich stepped down from his post as Labor Secretary in 1996 to spend more time with his teenage sons, Adam, now a sociology professor at Columbia University, and Sam, a writer and director who heads the video department at the popular comedy site CollegeHumor.com. (Reich and Clare Dalton divorced in 2012; he has since remarried.) Resuming the academic career he had embarked on in 1980 as a professor at Harvard’s John F. Kennedy School of Government, he took a position at Brandeis University and published a well-received serio-comic memoir about his years in the Clinton administration, Locked in the Cabinet.
