Transcript for Secret Service Agents Sent Home for Drinking
Now to more trouble for the secret service. Three members an elite unit responsible for protecting president Obama overseas have been sent home for drinking hours before going on duty. ABC's Jonathan Karl traveling with the president and joins us this morning in Brussels, Belgium. Good morning, Jon. Reporter: Good morning, robin. These were three members of the secret service's counterassault team allegedly so drunk one passed out in the hallway of the president's hotel. But it's important to point out this happened two days before the president had got here and the secret service says the president's security was never compromised but ever since that scandal involving prostitutes and secret service agents in Colombia, the secret service is having a zero tolerance policy for alcohol. That's why these three were disciplined and sent home. They don't want this trouble again with the agency. Jon, you were with the president as well yesterday and you asked him a question that is generating, well, a lot of attention this morning. Want to take a look. In light of recent developments, do you think Mitt Romney had a point when he said that Russia is America's biggest geopolitical foe if not Russia, who? Russia is a regional power that is threatening some of its immediate neighbors, not out of strength, but out of weakness. Russia's actions are a problem. They don't pose the number one national security threat to the United States. I continue to be much more concerned when it comes to our security with the prospect of a nuclear weapon going off in Manhattan. Reporter: That was the real provocative answer from the president. Real challenge to Vladimir Putin's pride. He, of course, sees Russia as a superpower, not simply a regional power, robin, we have had no response yet to that from the Russians. We should say it's making headlines out across the country. Here "The daily news" has a picture of what it would be like, what he was describing, a nuclear weapon here in Manhattan. Terrifying to even think about it, thank you, Jon.
