Who led a series of raids on suspected communist socialists and anarchists?

The series of raids on suspected communist, socialist, and anarchist groups, known as the Palmer Raids, was led by U.S. Attorney General A. Mitchell Palmer in 1919 and 1920. These raids were part of the broader Red Scare, fueled by fears of radical leftist movements following World War I. Palmer aimed to arrest and deport individuals deemed dangerous, resulting in thousands of arrests and significant civil liberties violations.
