A week into a scandal involving U.S. Secret Service agents – who allegedly brought prostitutes to their hotel in Colombia ahead of President Barack Obama’s arrival for a summit – reverberations continue in Washington. Several agents have been forced out of their jobs. Congress plans extensive hearings into a scandal that has tarnished the agency and embarrassed the White House.

As photos surfaced of one of the Colombian women allegedly involved, other details also have emerged – including the identities of two agents ousted so far from the agency.

David Chaney and Greg Stokes – both supervisors – are among the agents leaving. The agency has expanded its investigation to determine exactly how many personnel may have been involved.
