This is pretty monumental legislation being introduced by Senate Majority Leader Chuck Schumer, some highlights of the proposed amendment

All Federal Government records concerning unidentified anomalous phenomena should carry a presumption of immediate disclosure and all records should be eventually disclosed to enable the public to become fully informed about the history of the Federal Government’s knowledge and involvement surrounding unidentified anomalous phenomena.

(4) Legislation is necessary because credible evidence and testimony indicates that Federal Government unidentified anomalous phenomena records exist that have not been declassified or subject to mandatory declassification review as set forth in Executive Order 13526 (50 U.S.C. 3161 note; relating to classified national security information) due in part to exemptions under the Atomic Energy Act of 1954 (42 U.S.C. 2011 et seq.), as well as an over-broad interpretation of “transclassified foreign nuclear information”, which is also exempt from mandatory declassification, thereby preventing public disclosure under existing provisions of law.
