Speech on the Veto of the McCarran Internal Security Act

Harry S. Truman

September 22, 1950

…This is an omnibus bill containing many different legislative proposals with only one thing in common: they are all represented to be “anticommunist.” But when the many complicated pieces of the bill are analyzed in detail, a startling result appears.

H.R. 9490 would not hurt the Communists. Instead, it would help them.

It has been claimed over and over that this is an “anticommunist” bill—a “Communist control” bill. But in actual operation the bill would have results exactly the opposite of those intended…

It would help the Communists in their efforts to create dissension and confusion within our borders.

It would help the Communist propagandists throughout the world who are trying to undermine freedom by discrediting as hypocrisy the efforts of the United States on behalf of freedom.

Specifically, some of the principal objections to the bill are as follows:

  1. It would aid potential enemies by requiring the publication of a complete list of vital defense plants, laboratories, and other installations.
  2. It would require the Department of Justice and its Federal Bureau of Investigation to waste immense amounts of time and energy attempting to carry out its unworkable registration provisions.
  3. It would deprive us of the great assistance of many aliens in intelligence matters.
  4. It would antagonize friendly governments.
  5. It would put the Government of the United States in the thought-control business.
  6. It would make it easier for subversive aliens to become naturalized as U.S. citizens.
  7. It would give Government officials vast powers to harass all of our citizens in the exercise of their right of free speech.

Legislation with these consequences is not necessary to meet the real dangers which communism presents to our free society. Those dangers are serious and must be met. But this bill would hinder us, not help us, in meeting them. Fortunately, we already have on the books strong laws which give us most of the protection we need from the real dangers of treason, espionage, sabotage, and actions looking to the overthrow of our Government by force and violence. Most of the provisions of this bill have no relation to these real dangers…

The idea of requiring Communist organizations to divulge information about themselves is a simple and attractive one. But it is about as practical as requiring thieves to register with the sheriff. Obviously, no such organization as the Communist Party is likely to register itself voluntarily…

There is no more fundamental axiom of American freedom than the familiar statement: In a free country, we punish men for the crimes they commit, but never for the opinions they have. And the reason this is so fundamental to freedom is not, as many suppose, that it protects the few unorthodox from suppression by the majority. To permit freedom of expression is primarily for the benefit of the majority because it protects criticism, and criticism leads to progress.

We can and we will prevent espionage, sabotage, or other actions endangering our national security. But we would betray our finest traditions if we attempted, as this bill would attempt, to curb the simple expression of opinion. This we should never do, no matter how distasteful the opinion may be to the vast majority of our people. The course proposed by this bill would delight the Communists, for it would make a mockery of the Bill of Rights and of our claims to stand for freedom in the world…

We need not fear the expression of ideas—we do need to fear their suppression.

Our position in the vanguard of freedom rests largely on our demonstration that the free expression of opinion, coupled with government by popular consent, leads to national strength and human advancement. Let us not, in cowering and foolish fear, throw away the ideals which are the fundamental basis of our free society…

I do not undertake lightly the responsibility of differing with the majority in both Houses of Congress who have voted for this bill. We are all Americans; we all wish to safeguard and preserve our constitutional liberties against internal and external enemies. But I cannot approve this legislation, which instead of accomplishing its avowed purpose would actually interfere with our liberties and help the Communists against whom the bill was aimed.

This is a time when we must marshal all of our resources and all the moral strength of our free system in self-defense against the threat of Communist aggression. We will fail in this, and we will destroy all that we seek to preserve, if we sacrifice the liberties of our citizens in a misguided attempt to achieve national security…

No considerations of expediency can justify the enactment of such a bill as this, a bill which would so greatly weaken our liberties and give aid and comfort to those who would destroy us. I have, therefore, no alternative but to return this bill without my approval, and I earnestly request the Congress to reconsider its action. is a project of the Ashbrook Center at Ashland University
