Show notes: "We take a close look at Trump's tweets now that he's president. Can he make official policy statements on Twitter? And does that dictate government action? We explore the pros and cons when a president has a direct line to the people. This episode is co-hosted by Post reporter Abby Phillip and features interviews with Rutgers professor David Greenberg, former Obama digital strategist Laura Olin, data scientist David Robinson and former Rand Paul digital strategist Vincent Harris."
