FILE - In this April 26, 2014, file photo, Rep. Chris Stewart, R-Utah, waves to the audience during the Utah Republican Party nominating convention in Sandy, Utah. Stewart made $285,000 last year in book royalties, a good chunk of it for penning Elizabeth Smart's harrowing story of her kidnapping, rape and eventual rescue. Members of Congress are limited in outside income they can make from working — aside from investment money that keeps many of them well-off — but there's one way to bulk up their take-home pay: writing.
