NPR has been accused of displaying both liberal bias, as alleged in work such as a UCLA and University of Missouri study of "Morning Edition;" and conservative bias, including criticism of alleged reliance on conservative think-tanks. Public radio host Lisa Simeone, who worked for NPR from 1998 to 2002, accused NPR's Pentagon reporting of being "little more than Pentagon press releases." The NPR ombudsman has described how NPR's coverage of the Israel-Palestinian conflict has been simultaneously criticized as biased by both sides. University of Texas journalism professor and author Robert Jensen has criticized NPR as taking a pro-war stance during coverage of Iraq war protests.
