Final answer:
The first Red Scare resulted in Supreme Court cases dealing with free speech rights.
Step-by-step explanation:
The first Red Scare resulted in many Supreme Court cases dealing with free speech rights. During this time, fear of immigrants who might be communists or socialists led to the growth of nativism and restrictions on civil liberties. The case of Schenck v. United States in 1919 challenged the constitutionality of the Espionage and Sedition Acts, and the Supreme Court ruled in favor of the government's right to restrict free speech during times of war.
