Which member of president Wilson administration used Americans fear of communisim to illeagally arrest 5000 suspected communists?

A. Mitchell Palmer, the U.S. Attorney General during President Wilson's administration, used Americans' fear of communism to orchestrate the Palmer Raids in 1919. These raids resulted in the illegal arrest of around 5,000 suspected communists and radicals, often without proper warrants or evidence. Palmer's actions were driven by a desire to combat the perceived threat of communism following the Russian Revolution and rising labor unrest in the United States.
