Counterterror adviser: Obama's security not compromised by Secret Service Colombia conduct

The top White House counterterrorism adviser said Sunday that the Secret Service investigation into the prostitution scandal has so far shown President Obama's security "was not compromised" by agents' alleged misconduct ahead of Obama's arrival in Colombia.

John Brennan told "Fox News Sunday" that a "number of questions" remain about what happened in Cartagena, but the administration is satisfied the president was not put at risk.

"By all accounts the security and safety of the president was not compromised as a result of this, but (Secret Service Director Mark Sullivan) has put down the law as far as Secret Service behavior," Brennan said.

Brennan was referring to new conduct standards issued by the Secret Service which, among other rules, prohibit agents from letting foreign nationals into their hotel rooms aside from hotel staff or law enforcement. It also bars agents from frequenting "nonreputable" establishments.

Brennan praised Sullivan for the "aggressive and speedy action."
