Perdue: Congress has historic opportunity to make big deals

Sen. David Perdue, R-Ga., says President Trump is “a dealmaker first and last,” and that Americans can expect to hear a more conciliatory tone at the State of the Union on Tuesday despite the impasse over a southern border wall. Perdue joins Judy Woodruff to discuss whether the president will declare a national emergency and why he thinks House Speaker Nancy Pelosi should work with Trump.
