Federal judge calls out Barr for lying, orders previously withheld documents released

Rachel Maddow looks at former Attorney General Bill Barr's record of lying about the Mueller report, and outlines a federal judge's finding that Barr lied again about how the decision was made not to charge Donald Trump with obstruction of justice, ordering the release of never-before-seen material on that subject unless Attorney General Merrick Garland appeals that decision.
