Sen. Sasse on 'anti-tribes,' American tolerance for lies

In his new book “Them: Why We Hate Each Other--and How to Heal,” Sen. Ben Sasse, R-Neb, reflects on a growing “rootlessness” in America as local communities erode and our dependence on isolating technology grows. Judy Woodruff sits down with the senator, who also weighs in on the decay of truth in political discourse, his vision for government and how we can repair our fragmented society.
