Quite an explicit note:
Authorities closed the Lincoln Memorial on Monday after finding suspicious bottles in a restroom and a note reading “Do you know what anthrax is?” and “Do you know what a bomb is?”, a law enforcement official told The Associated Press.
Then there is a mysterious bottle containing a liquid:
Authorities found a bottle appearing to contain a liquid in a basement ladies’ rest room, along with the note, said an official from the Department of Homeland Security who asked to not be identified because his agency was not in charge of the incident.
Will update as news comes in.
