President Obama was briefed on an incident involving three drunken Secret Service agents and supports the agency director's “zero-tolerance approach” to such behavior, White House spokesman Jay Carney said Wednesday.

“He was briefed and I would refer you to the Secret Service in Washington and say generally [that] the president believes, as he has said in the past, that everybody representing the United States of America overseas needs to hold himself or herself to the highest standards,” Carney told reporters aboard Air Force One, en route to Rome with the president.

He added that Obama supports Secret Service Director Julia Pierson’s “zero-tolerance approach, on these matters.”

Three Secret Service agents were found drunk after a night out in the Netherlands, where they were preparing for Obama's week-long trip to Europe, according to reports. The agents were sent home on Sunday.

The incident is only the latest embarrassment for the agency and comes two years after a number of agents were sent home from Colombia after they were found to be drinking and consorting with prostitutes ahead of Obama's visit to the 6th Summit of the Americas.
