BLITZER: Lisa Sylvester's monitoring some of the other top stories in the SITUATION ROOM right now. Lisa, what do you have?</s>SYLVESTER: Hi there, Wolf. Well, in Philadelphia, investigators are trying to identify a suspicious white powder found in the building that houses the liberty bell. A guard found the powder inside a balloon. Details, though, are still sketchy. An FBI spokesman said that it is some kind of a biological substance. We're told, though, only a few people came in contact with it. The Liberty Bell Centre and part of a nearby street were evacuated. And you might think the infamous White House party crashers, remember them, that they would have stayed away from the Obamas' second state dinner? Well, guess again, Michaele and Tariq Salahi were in a limousine that was stopped by a secret service officer just a few blocks from the White House last night. The driver was ticketed after running a red light. The Salahis then went to dinner with friends at a nearby restaurant with cameras and photographers in tow. And French officials say a single masked intruder made off with millions of dollars worth of artwork from a French museum. Five paintings were stolen from the Paris museum of modern art, including major works by Picasso and Matisse. Officials say the thief got in by cutting a padlock on a gate and breaking into a window. The museum security camera reportedly was turned off, and, wolf, there were three guards on duty, and they said they did not see a thing. Sounds like something out of a movie a little bit.</s>BLITZER: Sounds like an inside job or something, who knows. All right, thanks very much, Lisa. We're getting our first live look at the massive oil spill gushing into the Gulf of Mexico, but why don't we know exactly how much oil is coming out? My interview with the EPA administrator, Lisa Jackson that's just ahead. And I'm also sitting down here in the SITUATION ROOM with the former president of Pakistan, Pervez Musharraf.
