live pictures from what we've been calling the leak cam. as you can see, there is nothing leaking now. so far the capping stack is holding, we presume. otherwise engineers would have started venting oil to relieve the oil. probably relieving some political pressure on the white house, which has take answer lot of fire over the last 80 or so days for it is handling of the crisis. henry joins us now. ed, what are you hearing? >> reporter: earlier today the president was giving a statement on the south lawn of the white house, reacting to the fact that the cap was if place. he told me that he sees this as a positive development. as you noted, these tests are still ongoing. the president said that he doesn't want to get ahead of that. he's planning on making a statement before he heads out on a weekend to maine.
