Ralph Nader on Single Payer, Climate Devastation, Impeachment & Why Mulvaney Is a "Massive Outlaw"

As President Trump threatens to shut down the federal government over border wall funding, there have been some shake-ups in the White House. Interior Secretary Ryan Zinke will resign as he faces at least 17 federal investigations into suspected ethics violations. A former fossil fuel industry lobbyist, David Bernhardt, will become the interim interior secretary. Meanwhile, Trump has tapped Mick Mulvaney to become acting chief of staff to replace Gen. John Kelly. Mulvaney already holds two posts in the administration: White House budget director and acting director of the Consumer Financial Protection Bureau. And in Texas, a federal court has declared the Affordable Care Act's individual mandate unconstitutional, setting up a likely challenge at the Supreme Court. We are joined by longtime consumer advocate and former presidential candidate Ralph Nader. He is author of the new book "To the Ramparts: How Bush and Obama Paved the Way for the Trump Presidency, and Why It Isn't Too Late to Reverse Course."
