Step-by-step explanation:
The constitutional issue at the center of the controversy over the enactment of the Sedition Act during World War I was freedom of speech.
The Sedition Act, passed by Congress in 1918, made it illegal to criticize the government, the draft, or the war effort. It restricted the rights of American citizens to voice their dissenting opinions and led to the prosecution of thousands of individuals.
The Supreme Court upheld the act in the case of Schenck v. United States, ruling that during times of war, the government could restrict speech that presents a "clear and present danger" to national security.
