Dent: Trump loyalty as new GOP ‘litmus test’ is troubling

Republican Rep. Charlie Dent of Pennsylvania says Congress is going to be “a lot worse off” without Sen. Jeff Flake, who announced on Tuesday that he wouldn’t seek re-election due to the current political climate. Dent, who has also said he won’t run again in 2018, joins Judy Woodruff to discuss the need for lawmakers to act as a check on the president, plus the outlook for tax reform.
