Paul Bender joins the Think Tank to discuss several legal elements of the investigation into President Donald Trump’s campaign. We ask him about:

• After asking others in the room to leave, Trump asked then-FBI Director James Comey to kill an investigation into former National Security Advisor Michael Flynn, saying, “I hope you can let this go.” Does this approach obstruction of justice?
• Comey did not comply and was fired? Given this, does Trump’s action constitute obstruction of justice?
• This request was reflected in Comey’s contemporaneous notes. Trump’s version is different. How do you assess their relative credibility if it comes down to he said-he said?
• How does the appointment of a special prosecutor change matters?

This and more in this week’s Think Tank.
