[249 U.S. 47, 48] Messrs. Henry John Nelson and Henry Johns Gibbons, both of Philadelphia, Pa., for plaintiffs in error.

Mr. John Lord OBrian, of Buffalo, N. Y., for the United States.

Mr. Justice HOLMES delivered the opinion of the Court.

This is an indictment in three counts. The first charges a conspiracy to violate the Espionage Act of June 15, 1917, c. 30, tit. 1, 3, 40 Stat. 217, 219 (Comp. St. 1918, 10212c), by causing and attempting [249 U.S. 47, 49] to cause insubordination, &c., in the military and naval forces of the United States, and to obstruct the recruiting and enlistment service of the United States, when the United States was at war with the German Empire, to-wit, that the defendant wilfully conspired to have printed and circulated to men who had been called and accepted for military service under the Act of May 18, 1917, c. 15, 40 Stat. 76 (Comp. St. 1918, 2044a-2044k), a document set forth and alleged to be calculated to cause such insubordination and obstruction. The count alleges overt acts in pursuance of the conspiracy, ending in the distribution of the document set forth. The second count alleges a conspiracy to commit an offense against the United States, to-wit, to use the mails for the transmission of matter declared to be non-mailable by title 12, 2, of the Act of June 15, 1917 (Comp. St. 1918, 10401b), to-wit, the above mentioned document, with an averment of the same overt acts. The third count charges an unlawful use of the mails for the transmission of the same matter and otherwise as above. The defendants were found guilty on all the counts. They set up the First Amendment to the Constitution forbidding Congress to make any law abridging the freedom of speech, or of the press, and bringing the case here on that ground have argued some other points also of which we must dispose.

It is argued that the evidence, if admissible, was not sufficient to prove that the defendant Schenck was concerned in sending the documents. According to the testimony Schenck said he was general secretary of the Socialist party and had charge of the Socialist headquarters from which the documents were sent. He identified a book found there as the minutes of the Executive Committee of the party. The book showed a resolution of August 13, 1917, that 15,000 leaflets should be printed on the other side of one of them in use, to be mailed to men who had passed exemption boards, and for distribution. Schenck personally attended to the printing. On [249 U.S. 47, 50] August 20 the general secretarys report said Obtained new leaflets from printer and started work addressing envelopes &c. and there was a resolve that Comrade Schenck be allowed $125 for sending leaflets through the mail. He said that he had about fifteen or sixteen thousand printed. There were files of the circular in question in the inner office which he said were printed on the other side of the one sided circular and were there for distribution. Other copies were proved to have been sent through the mails to drafted men. Without going into confirmatory details that were proved, no reasonable man could doubt that the defendant Schenck was largely instrumental in sending the circulars about. As to the defendant Baer there was evidence that she was a member of the Executive Board and that the minutes of its transactions were hers. The argument as to the sufficiency of the evidence that the defendants conspired to send the documents only impairs the seriousness of the real defence.

It is objected that the documentary evidence was not admissible because obtained upon a search warrant, valid so far as appears. The contrary is established. Adams v. New York, 192 U.S. 585, 24 Sup. Ct. 372; Weeks v. United States, 232 U.S. 383, 395, 396 S., 34 Sup. Ct. 341, L. R. A. 1915B, 834, Ann. Cas. 1915C, 1177. The search warrant did not issue against the defendant but aga
