Internal Security Act of 1950 (McCarran Act)–along with Truman’s veto message
U.S. Statutes at Large, 81st Cong., 2nd Sess., Chp. 1024, p. 987-1031
To protect the United States against certain un-American and subversive activities by requiring registration of Communist organizations, and for other purposes.
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That this Act may be cited as the ”Internal Security Act of 1950”.
Sec. 2. As a result of evidence adduced before various committees of the Senate and House of Representatives, the Congress hereby finds that-
(1) There exists a world Communist movement which, in its origins, its development, and its present practice, is a world-wide revolutionary movement whose purpose it is, by treachery, deceit, infiltration into other groups (governmental and otherwise), espionage, sabotage, terrorism, and any other means deemed necessary, to establish a Communist totalitarian dictatorship in the countries throughout the world through the medium of a world-wide Communist organization . . .
(6) The Communist action organizations so established and utilized in various countries, acting under such control, direction, and discipline, endeavor to carry out the objectives of the world Communist movement by bringing about the overthrow of existing governments by any available means, including force if necessary, and setting up Communist totalitarian dictatorships which will be subservient to the most powerful existing Communist totalitarian dictatorship. Although such organizations usually designate themselves as political parties, they are in fact constituent elements of the world-wide Communist movement and promote the objectives of such movement by conspiratorial and coercive tactics, instead of through the democratic processes of a free elective system or through the freedom-preserving means employed by a political party which operates as an agency by which people govern themselves.
(7) In carrying on the activities referred to in paragraph (6), such Communist organizations in various countries are organized on a secret, conspiratorial basis and operate to a substantial extent through organizations, commonly known as ”Communist fronts”, which in most instances are created and maintained, or used, in such manner as to conceal the facts as to their true character and purposes and their membership. One result of this method of operation is that such affiliated organizations are able to obtain financial and other support from persons who would not extend such support if they knew the true purposes of, and the actual nature of the control and influence exerted upon, such ”Communist fronts”. . . .
(9) In the United States those individuals who knowingly and willfully participate in the world Communist movement, when they so participate, in effect repudiate their allegiance to the United States, and in effect transfer their allegiance to the foreign country in which is vested the direction and control of the world Communist movement. . . .
(15) The Communist movement in the United States is an organization numbering thousands of adherents, rigidly and ruthlessly disciplined. Awaiting and seeking to advance a moment when the United States may be so far extended by foreign engagements, so far divided in counsel, or so far in industrial or financial straits, that overthrow of the Government of the United States by force and violence may seem possible of achievement, it seeks converts far and wide by an extensive system of schooling and indoctrination. Such preparations by Communist organizations in other countries have aided in supplanting existing governments. The Communist organization in the United States, pursuing its stated objectives, the recent successes of Communist methods in other countries, and the nature and control of the world Communist movement itself, present a clear and present danger to the security of the United States and to the existence of free American institutions, and make it necessary that Congress, in order to provide for the common defense, to preserve the sovereignty of the United States as an independent nation, and to guarantee to each State a republican form of government, enact appropriate legislation recognizing the existence of such worldwide conspiracy and designed to prevent it from accomplishing its purpose in the United States.
Employment of Members of Communist Organizations
Sec. 5. (a) When a Communist organization, as defined in paragraph (5) of section 3 of this title, is registered or there is in effect a final order of the Board requiring such organization to register, it shall be unlawful-
(1) For any member of such organization, with knowledge or notice that such organization is so registered or that such order has become final-
(A) in seeking, accepting, or holding any nonelective office or employment under the United States, to conceal or fail to disclose the fact that he is a member of such organization; or
(B) to hold any nonelective office or employment under the United States; or
(C) in seeking, accepting, or holding employment in any defense facility, to conceal or fail to disclose the fact that he is a member of such organization; or
(D) if such organization is a Communist-action organization, to engage in any employment in any defense facility . ..
Registration and Annual Reports of Communist Organizations
Sec. 7. (a) Each Communist-action organization (including any organization required, by a final order of the Board, to register as a Communist-action organization) shall, within the time specified in subsection (c) of this section, register with the Attorney General, on a form prescribed by him by regulations, as a Communist-action organization.
(b) Each Communist-front organization (including any organization required, by a final order of the Board, to register as a Communist-front organization) shall, within the time specified in subsection (c) of this section, register with the Attorney General, on a form prescribed by him by regulations, as a Communist-front organization . . .
Use of the Mails and Instrumentalities of Interstate or Foreign Commerce
Sec. 10. It shall be unlawful for any organization which is registered under section 7, or for any organization with respect to which there is in effect a final order of the Board requiring it to register under section 7, or for any person acting for or on behalf of any such organization-
(1) to transmit or cause to be transmitted, through the United States mails or by any means or instrumentality of interstate or foreign commerce, any publication which is intended to be, or which it is reasonable to believe is intended to be, circulated or disseminated among two or more persons, unless such publication, and any envelope, wrapper, or other container in which it is mailed or otherwise circulated or transmitted, bears the following, printed in such manner as may be provided in regulations prescribed by the Attorney General, with the name of the organization appearing in lieu of the blank: ”Disseminated by ____________, a Communist organization”; or
(2) to broadcast or cause to be broadcast any matter over any radio or television station in the United States, unless such matter is preceded by the following statement, with the name of the organization being stated in place of the blank: ”The following program is sponsored by ____________, a Communist organization.” . . .
Subversive Activities Control Board
Sec. 12. (a) There is hereby established a board, to be known as the Subversive Activities Control Board, which shall be composed of five members, who shall be appointed by the President, by and with the advice and consent of the Senate. Not more than three members of the Board shall be members of the same political party . . . It shall be the duty of the Board-
(1) upon application made by the Attorney General under section 13(a) of this title, or by any organization under section 13(b) of this title, to determine whether any organization is a ”Communist-action organization” within the meaning of paragraph (3) of section 3 of this title, or a ”Communist-front organization” within the meaning of paragraph (4) of section 3 of this title; and
(2) upon application made by the Attorney General under section 13(a) of this title, or by any individual under section 13(b) of this title, to determine whether any individual is a member of any Communist-action organization registered, or by final order of the Board required to be registered, under section 7(a) of this title . . .
