Here is an interview with him about his work with McCain.
About Stephen (from his website)
Stephen Crowley approaches his work with the same sense of exploration and wonder as when he was armed with a “Polaroid Swinger” at the age of 13. Over the last 25 years he has tried to find insightful moments in the midst of breaking national and international news that can sometimes define, in a single image, politics and culture. In his personal work Crowley searches for morsels of humanity, irony and humor, collecting images of the country’s character as hinted by physical structures, shifting light patterns and happenstance.On Feb. 5, 2002, Crowley, a graduate of the photography program at Daytona State College, was cited as “Photographer of the Year” by the White House News Photographers’ Association for a portfolio that included his essays “Voices of Afghanistan” and “A Day in the Life of President Bush.” In 2002 the Pulitzer Prize for Feature Photography was awarded to Crowley and four other photographers at The New York Times for work produced during the war in Afghanistan. That same year he received an honorary Doctor of Fine Arts degrees from the Corcoran College of Art + Design in Washington, D.C. In 2005 American Photo Magazine included Crowley on its list of the 100 Most Important People in Photography.His personal photography has been exhibited in shows at the Library of Congress, The National Geographic Society, and the Corcoran Art Museum.
