The chair of the House Ways and Means Committee formally requested six years of Trump’s personal and business tax returns earlier this month. Trump has said he won’t turn them over—and that the law is “100 percent” on his side. He’s 100 percent wrong about that. David Cay Johnston explains why the IRS director is required to hand over the returns—or face five years in jail—and also what we’re likely to find in Trump’s tax returns: his tax cheating and his money laundering for Russian oligarchs. David is a Pulitzer Prize–winning investigative reporter who is founder and editor of DCReport.org.

But who is this Stephen Miller? He grew up in liberal Santa Monica—what happened? What went wrong? Laurie Winer reports—she wrote about Stephen Miller for LA Magazine.
