Like most law enforcement agencies, the vast majority of members of the U.S. Secret Service are dedicated and highly capable at what they do. Because part of the agency's job is safeguarding the president of the United States and other high-ranking government officials and their families, it is imperative that Secret Service agents be above reproach.
Some of them are not, as Americans learned several weeks ago in a scandal involving some agents and prostitutes in Colombia. Those found to have shirked their duties have been fired.
Now a U.S. Senate investigative panel is looking into the Secret Service - and it is uncovering records of other wrongdoing by agents. Most of it appears to involve incidents such as sexually suggestive email messages that probably would not affect agents' ability to do their jobs.
Panel Chairman Sen. Joseph Lieberman, I-Conn., has said more serious allegations of misconduct, including at least one inappropriate relationship between an agent and a foreign national, are involved.
If senators find more house cleaning is needed at the Secret Service, it should be undertaken.
