Ex-CIA agent sues Cheney:

The civil lawsuit cites "a conspiracy among current and former high-level officials in the White House" to "discredit, punish and seek revenge against" Mr Wilson for publicly disputing statements made by Mr Bush justifying the war in Iraq.

While no specific dollar amount is requested, the lawsuit seeks unspecified compensatory and punitive damages and attorneys' fees and costs.

The suit also names Mr Libby, who was Mr Cheney's former chief of staff, and 10 unnamed senior government officials and aides.
