BLITZER: Right now, there's some dramatic new information emerging about the poisoning of a former Russian spy and his daughter in England. Sources tell CNN that British police have identified two suspects in the Novichok attack on Sergei Skripal and his daughter, Yulia. CNN's international diplomatic editor, Nic Robertson, is on the seen in Salisbury, where the poisoning occurred. Nic, what's the latest? What have you found?</s>NIC ROBERTSON, CNN INTERNATIONAL DIPLOMATIC EDITOR: Wolf, right behind me is the house Sergei Skripal was living in. It's ground zero for the investigators. It's a potential danger to citizens living around here. It has a permanent police cordon. It's still part of an active crime scene here. What the police seem to have discovered could be a very helpful and useful lead in all of this. A source familiar with the investigation has told CNN that the British authorities were able to pick up a coded Russian transmission to Moscow soon after the attack that said the two attackers had left the country. What police have been able to do after that is sort of work backwards from that, take all the close- circuit security footage they could find here in Salisbury and at border crossings and cross-check it, try to narrow down who the attackers could be. They're using high-tech facial recognition technology. They believe they've narrowed it down to two people. Having said that, they believe they were traveling under aliases. We also understand that, as far as the police are aware at the moment, these two individuals were not previously known to British intelligence authorities, which, again, although this is an important discovery, again, gives you an indication of how much more leg work needs to be done on the investigation -- Wolf?</s>BLITZER: Good point. Nic Robertson on the scene for us. Thank you very much. President Trump now wading unexpectedly to a very, very sensitive arena, making some strong comments about the Federal Reserve. The president is not supposed to get involved in that. We'll assess, give you the latest right after this.
