UK correspondent Gavin Grey told Ryan Bridge there's major security concerns for Swift's five Wembley Stadium shows, which kick off Thursday. “Naturally as you can imagine, high alert here in London as those teenagers are being questioned in Austria.” LISTEN ABOVESee omnystudio.com/listener for privacy information.
