Is It Legal for Trump to Block You on Twitter? Maybe Not

Joshua Geltzer was quoted in Salon on President Trump's use of Twitter and its intersection with the First Amendment:

"Trump's Twitter is very clearly the best place to go if you want to know what the president is saying," Joshua Geltzer, the executive director of Georgetown University's Institute for Constitutional Advocacy and Protection, told Salon. His group is one of several that have filed friend-of-the-court briefs in support of the Knight lawsuit.

Geltzer also argues that since Trump engages in dialogue with his Twitter followers and also interacts with accounts that do not follow him, Trump himself clearly regards his account as a public space.

"Trump might have a better rejoinder if his feed were just about broadcasting messages instead of the way that he uses it to converse," Geltzer said.
