THE FOLLOWING IS THE ORIGINAL THAT WAS REPLACED:
Except as provided in section 1461 of this title and this section, no funds authorized to be appropriated to the United States Information Agency shall be used to influence public opinion in the United States, and no program material prepared by the United States Information Agency shall be distributed within the United States. This section shall not apply to programs carried out pursuant to the Mutual Educational and Cultural Exchange Act of 1961 (22 U.S.C. 2451 et seq.). The provisions of this section shall not prohibit the United States Information Agency from responding to inquiries from members of the public about its operations, policies, or programs.

IT DOES ALLOW THE MATERIAL TO BE DISSEMINATED WITHIN THE US:
Such material may be made available within the United States and disseminated, when appropriate, pursuant to sections 502 and 1005 of the United States Information and Educational Exchange Act of 1948 (22 U.S.C. 1462 and 1437),
