Last week, before President Trump pardoned former Maricopa County Sheriff Joe Arpaio, my next guest told my colleague Jimmy Jenkins that a pardon in Arpaio’s case would be "really, really rare."
Now that the president has formally pardoned Arpaio, we wanted to check back in with Robert Weisberg to get his take on it. Weisberg is a professor of criminal law at Stanford and co-director of the school’s Criminal Justice Center.
