News nearly a dozen Secret Service agents sent to Colombia to protect President Barack Obama were sent home for misconduct should shock - and worry - Americans.
Secret Service agents are sent in advance to destinations where presidential visits are planned. Some of those dispatched to Cartagena, Colombia, took women who may have been prostitutes to their rooms, according to reports.
The many dangers of such behavior are obvious - and no doubt, Secret Service agents are aware of them.
Misconduct by federal officials and employees who waste taxpayers' money is bad enough. But when misdeeds risk chipping away at the cordon protecting the president of the United States, they are positively frightening.
Obama should be able to rely on everyone in his Secret Service detail. Clearly, he cannot. That needs to be investigated - and corrected, whatever it takes.
