RALEIGH, N.C. – Officials at North Carolina State University are working to figure out who wrote disparaging comments about President-elect Barack Obama in a tunnel designated for free speech.
 
N.C. State police Capt. Jon Barnwell said someone used spray paint to write comments about Obama that bordered on threatening. The Free Expression Tunnel was built in 1939 to allow people to express their first-amendment rights.
 
Barnwell said someone noticed the writing before classes began Wednesday.

N.C. State officials responded by painting the tunnel white, saying the negative expressions had gone over the edge of what was acceptable. Barnwell said anyone with information on who left the messages is asked to contact campus police
