Ag commissioner says more tests may be done

BISMARCK, N.D. (AP) - North Dakota Agriculture Commissioner Doug Goehring (GOH'-ring) says doctors have been unable to determine the cause of his symptoms and more tests may be done.

Goehring checked into a Bismarck hospital earlier this week after being extremely fatigued and feeling an unusual sensation in his hands and feet.

He says he's continuing to work from the hospital.
