50 U.S. Code § 1702 (b) The authority granted to the President by this section does not include the authority to regulate or prohibit, directly or indirectly—
(3) the importation from any country, or the exportation to any country, whether commercial or otherwise, regardless of format or medium of transmission, of any information or informational materials, including but not limited to, publications, films, posters, phonograph records, photographs, microfilms, microfiche, tapes, compact disks, CD ROMs, artworks, and news wire feeds.
