does freedom of speech protect all speech including lies?

Depending on the context the answer can either be “yes” or “no”. In New York Times v Sullivan (1964) the Court extended First Amendment protection to false Statements. However, 18 U.S.C. 1001 makes it a crime to “knowingly make any material false, fictitious, or fraudulent statements towards federal agents”. So it really does just depend on the situation.
