Stephen Colbert needled President-elect Joe Biden over his alleged run-in with a Delaware gangster when the late-night host asked for his reaction to critics suggesting his wife Jill should drop her doctoral title.

During a Thursday interview, the CBS comic asked Biden, “as a husband,” whether he wanted “to get out a length of pool chain and go full Corn Pop” on people who agreed with an incendiary Wall Street Journal op-ed that argued his second wife should stop referring to herself as “doctor” when her doctorate was in education and not medicine.
