The Obama administration announced Thursday that it has ordered BP to release all data related to the massive spill, including environmental sampling analyses, internal investigation reports and details of the cleanup effort. In a letter to BP Group CEO Tony Hayward, Homeland Security Secretary Janet Napolitano and Environmental Protection Agency Administrator Lisa Jackson told BP to post that information on a website and update it daily.

"The public and the United States government are entitled to nothing less than complete transparency in this matter," they concluded.
