Iowa Gov. Terry Branstad remains in a Des Moines hospital, where he is receiving treatment for what doctors believe is a viral illness and dehydration.

Branstad spokesman Jimmy Centers didn't provide a condition update Tuesday morning, but said more information about the governor's status will be released when it becomes available. Branstad's public appearances for the day have been canceled.

Branstad was taken by ambulance to Iowa Methodist Medical Center in Des Moines on Monday after he required assistance at a ribbon-cutting event. 

Doctors said they believed the governor has a viral illness. The hospital conducted tests and ruled out other contributing factors, including cardiac issues for which he's been previously treated.
