Lawrence: Hillary Clinton didn't know Epstein. Melania Trump did. When will Melania Trump testify?

Tonight on The Last Word: Hillary Clinton testifies “I never knew Jeffrey Epstein." Also, ICE and the CBP reportedly spent $144 million on weapons and munitions. Plus, the Justice Department says it’s reviewing if Epstein documents were improperly withheld. And a new television series, “The Gray House," tells a Civil War resistance story. Rep. Suhas Subramanyam, Sen. Adam Schiff, Andrew Weissmann, and Morgan Freeman join Lawrence O’Donnell.
