(CNN) -- Fallout from a job discrimination lawsuit filed by the head of the Immigration and Customs Enforcement office in New York has led to at least a temporary shakeup at the agency's headquarters in Washington. Suzanne Barr, chief of staff for ICE Director John Morton, voluntarily stepped down this week and is on paid leave because of allegations made against her as part of an ongoing civil suit filed by New York ICE chief James Hayes. In the suit, which is leveled at the Department of Homeland Security and DHS Secretary Janet Napolitano, Hayes claims he was passed over for promotions in favor of less-qualified women, some of whom used to work for Napolitano when she was governor of Arizona. As part of his lawsuit, Hayes cites behavior by Barr in an attempt to prove an alleged culture of sexual discrimination against men, according to Hayes' lawyer, Morris Fischer of Maryland.
