Seth takes a closer look at the Trump White House as they peddle conspiracy theories, attack immigrants and defend an aide accused of domestic violence.
John Mulaney describes why the Rock and Roll Hall of Fame Induction Ceremony is like a wedding - if every speech was given by the bride's ex-boyfriend - and what it's like to see Frank Sinatra in concert.
John then speaks to Late Night producer Kevin Miller backstage at Studio 8G for a few more questions backstage.
Next, Seth speaks to Congressman Seth Moulton about the popular Iraqi TV show he hosted during his time in the Marine Corps and why more veterans like him should challenge establishment politics by taking on incumbents.
Rep. Moulton then speaks to Late Night producer Henry Melcher backstage at Studio 8G.
