Perhaps you’ve heard: Special counsel Robert Mueller testified on Wednesday. There’s plenty of analysis about who won and who didn’t. We’re skipping that part. Instead, on a special, speedy episode of Trump, Inc. we’re focusing on the few tidbits that were actually revealing and how it came to be that there weren’t more. ProPublica’s Jesse Eisinger and Heather Vogell talk with WNYC’s Andrea Bernstein about the many things we didn’tlearn and why. They discuss potential mistakes during the investigation, avenues Mueller didn’t explore and witnesses — like the president — he decided not to try to question in person.Mueller’s testimony is over. His report is done. And his office is closed. But there are plenty of critical yet unanswered questions remaining. And we’re still digging. Listen to the episode to hear what we still want to know.
