WATCH: Dem Impeachment Manager says Trump is “guilty of the worst and highest crimes & misdemeanors”

Appearing on MSNBC with Lawrence O’Donnell, House impeachment manager Rep. Madeleine Dean made the case that President Trump is “guilty of the worst and highest crimes & misdemeanors.”

Dean argued Trump incited an insurrection, and said Trump’s “series of lies radicalized” his supporters to attack the Capito.

“He lit the match… and sadly he played on these people’s fears and ignorance,” Dean told O’Donnell.
