LISA SYLVESTER, CNN CORRESPONDENT: I'm Lisa Sylvester. Here are some of the top stories in the SITUATION ROOM right now. Organic foods, apparently, don't contain any more vitamins or nutrients than regular foods despite costing up to twice as much money. That is according to researchers from Stanford University who looked at more than 200 studies comparing the two categories. They did find that organic produce and meat contained fewer pesticides, but they couldn't say whether the difference was enough to have an effect on people's health. And first on CNN, the commander of U.S. NAVY SEALs has sent all 2,500 of them a harsh message saying, quote, "He's disappointed, embarrassed and concerned that some of them are speaking publicly about their secret missions and training." CNN exclusively obtained a copy of the message from Rear Admiral Sean Pybus. The highly anticipated book, "No Easy Day," written by a Navy SEAL about the Osama Bin Laden raid comes out today. And GQ is reporting that vice presidential nominee, Paul Ryan, that he has chosen his new secret service codename. Inspired by his love of hunting, he's going to be known as Bowhunter. His wife, Janna, is going by Buttercup which is reportedly a nickname her husband uses for her, and the Ryans received secret service protection last month after Paul Ryan was named Mitt Romney's running mate. And democrats drop a reference to Jerusalem as Israel's capital in a reference to Israel as America's strongest ally in the region. Could that hurt them in November? And our latest poll shows independent voters moving toward Mitt Romney. Wolf Blitzer is back to ask a pair of top Democrats what that's all about.
