Senior lawmakers are calling on President Donald Trump to allow the release of remaining government records on the assassination of President John F. Kennedy.

Resolutions introduced in the House and Senate would call on the president to allow release of documents held by the National Archives and Records Administration, and for the Archives to work to meet a statutory deadline that arrives later in October.

The deadline occurs because it will be the 25th anniversary of the signing of the President John F. Kennedy Assassination Records Collection Act.

The leaders of the Senate resolution are Judiciary Chairman Charles E. Grassley of Iowa and Democratic Sen. Patrick J. Leahy of Vermont, who is a former chairman of the committee.

“The assassination of President Kennedy was one of the most shocking and tragic events in our nation’s history,” Leahy said in a statement. “Americans have the right to know what our government knows. Transparency is crucial for our country to fully reckon with this national tragedy, and that is the purpose of these resolutions.”
