We are excited to hear Marc Ambinder talk about discovering and countering misinformation online.  He is the Digital Security and Counter-Disinformation Fellow at USC Annenberg.  After Marc's presentation in the first hour, and following discussion, we will then hear from Nick Greif, author of a Resolution calling for Sheriff Villanueva to resign.  We'll be voting on whether or not to support this resolution.  And of course, we'll have time to talk about the election.  Come join us!
