Answer:
The Palmer Raids contributed to the power of J. Edgar Hoover, as he was one of the leaders of the operations.
Explanation:
The Palmer Raids were the attempts by the United States Department of Justice to arrest and expel radical leftists and anarchists during Alexander Mitchell Palmer's term as Attorney General of the United States. Raids and arrests took place in November 1919 and January 1920 in the context of Red Scare, and were led by J. Edgar Hoover. Although more than 500 foreign citizens have been expelled, including a number of prominent left-wing leaders, Palmer's work had been slowed down by Department of Labor officials who, being responsible for the evictions, had opposed his methods.
