Attorney General Eric Holder announced that the Department of Justice will make public memos and opinions concerning warrantless surveillance, and other controversial claims of Presidential authority, that were prepared in the wake of 9/11. The documents describe the basis for President Bush's domestic surveillance program. After learning of the warrantless wiretap program, EPIC sued the Department of Justice under the Freedom of Information Act to compel disclosure of legal memos concerning the program. Government lawyers subsequently disavowed the justifications for the warrantless surveillance. The National Security Agency's Warrantless Surveillance Program was based on Office of Legal Council memos and opinions.
