Michael is joined by Mark Halperin to unpack two big political stories: what the latest primary results really say about the rise of democratic socialism inside the Democratic Party, and the unanswered questions surrounding a reported threat to Air Force One. Who traveled with President Trump after he was moved to another aircraft, who was left behind—and was the story leaked on purpose? Plus, a debate over polling, Trump’s inner circle, presidential security and the role of the White House press pool.
