Heather Mac Donald Sounds Off on College Protests, Ann Coulter, and 'Losing America' with Tucker Carlson

Conservative commentator and author Heather Mac Donald, whose event was shot down by protesters at Claremont McKenna College, sounds off on the challenge Ann Coulter faced at Berkeley, arguing we're in danger of 'losing America'.

Mac Donald, the author of "The War on Cops: How the New Attack on Law and Order Makes Everyone Less Safe," said that by inviting and then disinviting speakers to campus, "we're looking at pure viewpoint discrimination."
