The US government has revealed details of serious allegations against Secret Service agents and officers since 2004, including claims of involvement with prostitutes, leaking sensitive information, publishing pornography, sexual assault, illegal wiretaps, improper use of weapons and drunken behaviour.
It wasn't immediately clear how many of the accusations have been confirmed.
The heavily censored list, which is 229 pages long, was quietly released under the US Freedom of Information Act following the Secret Service prostitution scandal that erupted in Colombia in April.
It describes accusations filed against Secret Service employees with the Homeland Security Department's inspector general.
Some of the accusations occurred as recently as last month. The US government noted that some of the claims were resolved administratively, and others were being formally investigated.
The complaints included an alleged sexual assault reported in August 2011.
The new disclosures of so many serious accusations lend weight to concerns expressed by the US Congress that the prostitution scandal exposed a culture of misconduct in the Secret Service.
Secret Service Director Mark Sullivan apologised for the prostitution incident in May but insisted that what happened in Colombia was an isolated case.
