Until recently, Karoun worked as the sole Washington correspondent for the Las Vegas Sun, covering the White House, the federal courts, and Senate Majority Leader Harry Reid and the Nevada congressional delegation through two election cycles and many national debates about the economy, energy, immigration, housing and defense. Her articles either won or came in as runner up for the Washington Press Club Foundation’s David Lynch memorial award for best regional coverage of Congress in 2012, 2013 and 2014, and her video packages have appeared on the paper’s prize-winning website.
