Guest: Kathleen Hall Jamieson

Middle-of-the-night tweets with errant capitalization and grammar, vitriolic insults, flat out denials of known truths: We have never had a president who communicates quite like Donald Trump. KATHLEEN HALL JAMIESON, director of the Annenberg Public Policy Center at the University of Pennsylvania and co-founder of FactCheck.org, joins Marty for a conversation about the ways Trump’s rhetoric helped him win the election, and may be hurting him during his presidency.
