telling Palmer that he should "not let this country see red." Secretary of the Navy Josephus Daniels, who made notes of the conversation, thought the Attorney General had merited the President's "admonition", because Palmer "was seeing red behind every bush and every demand for an increase in wages." Palmer's supporters in Congress responded with an attempt to impeach Louis Post or, failing that, to censure him. The drive against Post began to lose energy when Attorney General Palmer's forecast of an attempted radical uprising on May Day 1920 failed to occur. Then, in testimony before the House Rules Committee on May 7–8, Post proved "a convincing speaker with a caustic tongue" and defended himself so successfully that Congressman Edward W. Pou, a Democrat presumed to be an enthusiastic supporter of Palmer, congratulated him: "I feel that you have followed your sense of duty absolutely." On May 28, 1920, the nascent American Civil Liberties Union (ACLU), which was founded in response to the raids, published its Report Upon the Illegal Practices of the United States Department of Justice, which carefully documented unlawful activities in arresting suspected radicals, illegal entrapment by agents provocateur, and unlawful incommunicado detention. Such prominent lawyers and law professors as Felix Frankfurter, Roscoe Pound and Ernst Freund signed it. Harvard Professor Zechariah Chafee criticized the raids and attempts at deportations and the lack of legal process in his 1920 volume Freedom of Speech. He wrote: "That a Quaker should employ prison and exile to counteract evil-thinking is one of the saddest ironies of our time." The Rules Committee gave Palmer a hearing in June, where he attacked Post and other critics whose "tender solicitude for social revolution and perverted sympathy for the criminal anarchists...set at large among the people the very public enemies whom it was the desire and intention of the Congress to be rid of." The press saw the dispute as evidence of the Wilson administration's ineffectiveness and division as it approached its final months.

He wrote that "a mob is a mob, whether made up of Government officials acting under instructions from the Department of Justice, or of criminals and loafers and the vicious classes." His decision effectively prevented any renewal of the raids. Palmer, once seen as
