The bi-partisan reforms are aimed principally at the Freedom of Information Act of 1966, which has not been updated in nearly a decade.
"Achieving the true consent of the governed requires informed consent, and such consent is possible only with an open and accessible government," Cornyn said.

Cornyn and Leahy are both members of the Senate Judiciary Committee.
