A former top Bush administration lawyer has admitted he knew the White House’s warrantless spy program was illegal. Speaking before the Senate Judiciary Committee Tuesday, Jack Goldsmith said he could not find legal support for certain aspects of the government surveillance program. Goldsmith did not specify what he found illegal. The White House has barred him from giving any key details. As the former head of the Office of Legal Counsel, Goldsmith was the Justice Department’s top legal adviser to the White House from 2003 to 2004.
