"There was no indication in the filing that either Bush or Cheney authorized Libby to disclose Valerie Plame's CIA identity.

But the disclosure in documents filed Wednesday means that the president and the vice president put Libby in play as a secret provider of information to reporters about prewar intelligence on Iraq.

The authorization came as the Bush administration faced mounting criticism about its failure to find weapons of mass destruction in Iraq, the main reason the president and his aides had given for going to war."
