During times of war or national crisis, Congress has passed laws that place limits on our First Amendment freedom of speech. In the landmark decision of Schenck v. United States, the Supreme Court held that — A. laws, such as the Smith Act, that limit free speech protect the country from the spread of Nazism and Communism

B. “symbolic speech” such as flag burning, meant to convey a political message, is illegal under the First Amendment

C. the publishing of critical anti-government statements with the “intent to defame” is
considered treason

D. language that presents a clear and present danger to national security is not protected by the First Amendment
