What was mailed to attorney general A. Mitchell Palmer?

A. Mitchell Palmer, the U.S. Attorney General during the Red Scare in the early 1920s, received a series of mail bombs in April 1919. These bombs were part of a coordinated campaign by anarchists and radical leftists aiming to intimidate government officials. One bomb detonated outside his home, while others targeted various public figures, highlighting the era's intense fears of political extremism and prompting Palmer to initiate a series of raids against suspected radicals, known as the Palmer Raids.
