Sen. Doug Jones introduced a new bill Tuesday to create a panel to systematically review, declassify, and release government documents and information related to unsolved criminal civil rights cases from decades ago.

Executive branch officials process Freedom of Information Act requests to see documents related to such cases too slowly, Jones’ office argued in a news release Tuesday, and the scope of what they hand over when they finally do can often be too narrow.

Pertinent congressional records related to the cases are not subject to FOIA requests. And some cases contain information from half a century ago that is still unnecessarily classified.

“Having prosecuted two civil rights cold cases in Alabama, I know firsthand the importance of having every available piece of information at your disposal,” the Alabama Democratic freshman said in a statement.

As a U.S. attorney in the early 2000s, Jones successfully prosecuted two Ku Klux Klan members involved in the 1963 Birmingham church bombing that killed four girls.
