U.S. Attorney General Memorandums 
The Holder Memo is part of series of policy memos on how federal agencies should apply FOIA exemptions. Beginning in 1977 with Attorney General Griffin Bell, and continued by Attorney General William French Smith in 1981 and Attorney General Janet Reno in 1993, U.S. Dept. of Justice (DOJ) has announced how the executive branch should approach FOIA, its application, and DOJ's defense of agency's actions. In other words, DOJ’s position on when they would defend in a FOIA suit has seesawed for about the last three decades.
Reno Memo 
The Reno Memo  established a "presumption" in favor of disclosure by providing that "it shall be the policy of the Department of Justice to defend the assertion of a FOIA exemption only in those cases where the agency reasonably foresees that disclosure would be harmful to an interest protected by that exemption." It encouraged all government agencies to review FOIA requests in a manner most favorable to openness and to release information, even though it might fall within one of the nine exemption categories, if no “foreseeable harm” would result from the disclosure. The goal was to achieve the “maximum responsible disclosure.”
Ashcroft Memo 
On October 12, 2001, Attorney General (AG) John Ashcroft issued a policy memorandum on FOIA to all federal executive agencies. The AG declared the Department of Justice (DOJ) would defend agencies’ decisions to withhold documents from a FOIA requester under one of the statute's exemptions "unless they lack a sound legal basis or present an unwarranted risk of adverse impact on the ability of other agencies to protect other important records."
The Ashcroft Memorandum reversed the Reno standard. Agencies were told that in making discretionary FOIA decisions they should carefully consider the fundamental values behind the exemptions – national security, privacy, government’s interests, etc. – and to lean in their favor whenever possible. The Ashcroft Memo  with its "sound legal basis" standard encouraged (or at least seemed to support) greater use of FOIA exemptions by federal agency personnel.
AG Holder Memo 
The Ashcroft Memo was rescinded by Attorney General Eric Holder on March 14, 2009. The AG Holder Memo appears to have reinstated the Reno Memo standard and extends the policy. The policy of the executive branch is to be open, responsive, transparent, and accountable. The current memo encourages the maximum disclosure possible in discretionary exemptions and to, whenever possible, reasonably segregate exempt information and release the rest.
