; and (B) by adding at the end the following new paragraph: (2) In the case of informational materials for or in the interests of a foreign principal which are transmitted or caused to be transmitted by an agent of a foreign principal by posting on an online platform, the agent shall ensure that the conspicuous statement required to be placed in such materials under this subsection is placed directly with the material posted on the platform and is not accessible only through a hyperlink or other reference to another source. (3) If the Attorney General determines that the application of paragraph (2) to materials posted on an online platform is not feasible because the length of the conspicuous statement required to be placed in materials under this subsection makes the inclusion of the entire statement incompatible with the posting of the materials on that platform, an agent may meet the requirements of paragraph (2) by ensuring that an abbreviated version of the statement, stating that the materials are distributed by a foreign agent on behalf of a clearly identified foreign principal, is placed directly with the material posted on the platform. (4) An online platform on which informational materials described in paragraph (2) are posted shall ensure that the conspicuous statement described in such paragraph (or, if applicable, the abbreviated statement described in paragraph (3)) is maintained with such materials at all times, including after the material is shared in a social media post on the platform, but only if the platform has 50,000,000 or more unique monthly United States visitors or users for a majority of months during the 12 months preceding the dissemination of the materials. . (2) Effective date The amendments made by paragraph (1) shall apply with respect to materials disseminated on or after the expiration of the 60-day period which begins on the date of the enactment of this Act, without regard to whether or not the Attorney General has promulgated regulations to carry out such amendments prior
