Washington ? The Bush administration has conducted an extensive spying operation on Prime Minister Nouri al-Maliki, his staff and others in the Iraqi government, according to a new book by Washington Post associate editor Bob Woodward.

“We know everything he says,” according to one of multiple sources Woodward cites about the practice in “The War Within: A Secret White House History, 2006-2008,” scheduled for release Monday.

The book is Woodward’s fourth to examine the inner debates of the Bush administration and its handling of the Iraq and Afghanistan wars. The Washington Post will run a four-part series based on the book beginning Sunday. Fox News published a report about the book on its Web site Thursday night after obtaining a copy ahead of the release date
