Kline was in "secure location"
This from the Strib explains Rep. Kline's absence from the State of the Union session last night. Maybe that's where Supreme Court Justices Scalia, Thomas and Alito were as well?
...According to Kline spokesman Troy Young, the congressman "was asked by security officials to view the proceedings from an alternate site close to the Capitol." That's all Young said he was authorized to say.
