Crime | Secret Service Booted Secret Service Agent Looks to Sue More resignations expected By Matt Cantor Posted Apr 20, 2012 8:47 AM CDT Copied US secret service agents walk around the Convention Center in Cartagena, Colombia.

Congress expects more resignations in the matter within days, according to Rep. Peter King. While reports have held that three agents have been forced to leave, a lawyer for two of them—David Chaney and Greg Stokes—says that's inaccurate, according to Reuters. "Nobody has been involuntarily separated from the agency as we speak today, nobody," he says. Though authorities have reportedly told Stokes he'll be fired, he is "vigorously defending himself from any of these accusations and will take full advantage of the administrative process that is available to him," Lawrence Berger says. While some officials fear that the scandal could be symptomatic of a larger pattern, ex-agents tell the Los Angeles Times that's not the case. "My opinion ... is that this is an anomaly," says one. "I never before heard of our folks being involved with prostitutes." Read These Next New Fox star, 23, misses first day after car troubles.
