Sen. Flake: It's not conservative to stay silent about Trump

In his new book “Conscience of a Conservative,” Sen. Jeff Flake, R-Ariz., examines where his own party has gone wrong, calls for a return to conservatism and criticizes the man at the top of the ticket. Sitting down with Judy Woodruff for a conversation, the Republican senator speaks out about President Trump but says he has “done nothing” that would force lawmakers to kick him out of office.
