The retirement comes after a tough year for the service, which was rocked by a prostitution scandal that resulted in the resignation or firing of six agents.

The data, going back to 2004, total 229 pages. The list does not detail confirmed cases of misconduct, but rather accusations of such misbehavior as involvement with prostitutes.

At the first congressional hearing into the scandal, Republican Sen. Susan Collins of Maine will make the case that Secret Service supervisors have turned a blind eye to bad behavior.

The rules cover alcohol consumption and the types of businesses traveling staff can patronize.

The agency has a pipeline of talent waiting in its field offices.

A CBS/KIRO-TV reporter says he's found evidence that Secret Service agents, along with military escorts, patronized a strip club in March, 2011, in El Salvador. That's a year before the current Secret Service scandal involving prostitutes in Colombia.

Top stories include: Republican presidential candidate Mitt Romney wins five primary state elections; there's a new report suggesting that Secret Service agents may have acted inappropriately on other official trips - several agents are accused of hiring prostitutes while in Colombia this month.

Some of the agents accused of cavorting with prostitutes in Colombia say similar behavior had been overlooked in the past, The Washington Post reports. Homeland Security Secretary Janet Napolitano says there's no evidence of that so far.

The president said those implicated should not detract from the rest of the Secret Service.
