U.S. Senator Mark Kirk Shaken Up Over Staffer Death

(Washington, D.C.) -- U.S. Senator Mark Kirk says he's pretty shaken up over the sudden death of one of his staffers, Lisa Radogno. He says the D.C. scheduler was one of the brightest personalities in his office, with a sense of humor like none other. The 31-year-old died from a massive pulmonary embolism Wednesday. Radogno was the daughter of Illinois Senate Minority Leader Christine Radogno.
