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.

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.
