In June, S. 2520 the FOIA Improvement Act was introduced into the Senate by Senators Patrick Leahy (D-VT), John Cornyn (R-TX) and Edward Markey (D-MA). Since then, according to OpenCongress.org, nothing has happened.
Congress goes out for the Summer after this week and is not back into session until September 8. For the bill to become law, it will need to go to the Judiciary Committee, reported and voted on by the floor and then go to conference with a similar but different House FOIA bill. Frankly, time may be running our a 2014 FOIA bill.
