The former "Crossfire" host has been diagnosed with a brain tumor and is suspending his journalistic work.
Novak issued a statement Monday saying the tumor was found Sunday after he had been rushed to Boston's Brigham and Women's Hospital from Cape Cod, where he was visiting his daughter.
The Chicago Sun-Times columnist says he is suspending his journalistic work for an indefinite, "but God willing, not too lengthy period." His statement did not say if the tumor was malignant.
Novak was the first to publicly reveal the name of CIA operative Valerie Plame.
Last week he was given a $50 citation after he struck a homeless man with his black Corvette in Washington. Novak kept going until he was stopped by a bicyclist.
