The Justice Department's Investigation of Vice President Spiro Agnew

In 1973, in the throes of the Watergate scandal, three young federal prosecutors uncovered a separate criminal scheme being run inside the White House — the sitting vice president, Spiro Agnew, was taking envelopes stuffed with cash in exchange for official acts as an elected official. If Nixon left office, Agnew would be the next President. And so, what would happen if the President was charged with a federal crime? Worse yet, what if he was convicted? Now that Donald Trump has been charged with 37 federal crimes – as he runs again for president — Rachel Maddow and Bag Man executive producer Mike Yarvitz talk with the three Spiro Agnew prosecutors who have the only experience in our nation’s history with a situation like this.
