Sen. Ted Cruz, the Texas Republican often mentioned as a possible presidential candidate, is working on a project considered standard for national contenders: a book. Cruz's literary agent, Keith Urbahn, said Wednesday that the tea party favorite had agreed to terms with HarperCollins. Urbahn declined to discuss the contents of the book, currently untitled and with no scheduled release date, or to confirm a report in the Washington Examiner that the deal was worth $1.5 million. But he says the number is "close."
