WASHINGTON - At the heart of Friday's indictment of a top White House aide remain two unsolved mysteries.

Who forged the documents that claimed Saddam Hussein was seeking uranium for nuclear weapons in the African country of Niger?

How did a version of the tale get into President Bush's 2003 State of the Union address, even though U.S. intelligence agencies never confirmed it and some intelligence analysts doubted it?

Former Ambassador Joseph Wilson, who found no substance to the alleged deal during a CIA-sponsored trip to Niger, accused Bush in July 2003 of twisting the intelligence.
