The White House has agreed to restore 94 days worth of e-mails that vanished during the Bush administration, a liberal watchdog group announced Monday.

Under a settlement announced Dec. 14, the Obama administration said it will rescue the missing e-mails from backup files, then send them to the National Archives and Records Administration for storage. It will also produce several boxes of documents relating to failures in the White House e-mail system and the Bush administration’s response to those problems.
