Valerie Plame Wilson

In July 2003, newspaper columnist Robert Novak published the name of undercover CIA operative Valerie Plame — shortly after Plame's husband, former ambassador Joseph Wilson, wrote an op-ed piece contradicting President Bush's contention that Saddam Hussein had tried to procure yellowcake uranium from the West African nation of Niger.

As a former counterterrorism official in the Clinton and Bush administrations, Richard A. Clarke often had to imagine worst-case scenarios. His first novel — a thriller — does just that: set five years in the future, it envisions the United States on the verge of another war in the Middle East.

Questions remain about who in the Bush administration outed CIA operative Valerie Plame. Adam Liptak of The New York Times and Anne Marie Squeo of The Wall Street Journal discuss the case and the subsequent jailing of the Times' Judith Miller for refusing to reveal her sources.
