On October 16, 2017, Professor Kevin O’Neill joined U.S. District Court Judge Dan Aaron Polster as co-presenters at a CLE seminar on First Amendment law hosted by the Cleveland Metropolitan Bar Association. The seminar, entitled “Politics on Social Media: First Amendment Implications,” focused on the use and abuse of social media by American politicians. Though more and more elected officials are using Twitter, Facebook, and other social media to communicate with their constituents, some politicians are blocking or censoring constituents who respond with criticism. The seminar reviewed and analyzed recent cases in which politicians were sued after trying to suppress criticism on social media, including a suit against President Trump for blocking some antagonistic Twitter followers.
