Question: Did both Davis v. Beason and Gitlow v. New York mention the First Amendment in their case? 
Sentence (from "Brandenburg v. Ohio"): In the process, "Whitney v. California" (1927) was explicitly overruled, and doubt was cast on "Schenck v. United States" (1919), "Abrams v. United States" (1919), "Gitlow v. New York" (1925), and "Dennis v. United States" (1951).
Relevant evidence: No
