park bench in this nondescript shopping center in the sleepy town of salisbury. just behind me, you see the police tent covering the parking bench. the entire area remains cordoned, the subject of an investigation. at the helm of the investigation, britain s counterterrorism police. they do not think this is terrorism. but they were brought in as a result of unusual circumstances, circumstances now being considered by the highest level of british government. and the reason why russia is a focus in all of this is because of who skripal is. he s a former russian intelligenceo intelligence operative. in 2016 he was convicted of spying for the u.s., released as part of a high-profile prison swap in 2010. he settled here in salisbury. now we understand he is in critical condition alongside his daughter in a british hospital. erin mclachlan live in england. appreciate it.
