(AP) - New Jersey Gov. Chris Christie is undergoing tests at a hospital after he had difficulty breathing.

Spokesman Michael Drewniak tells The Associated Press that the governor was being driven to a farm in central New Jersey when the governor had difficulty breathing. He says he was taken to Somerset Medical Center out of an "abundance of caution."

Drewniak says the 48-year-old suffers from asthma and all indications are Christie "will be fine."

Christie had been due to sign open-space legislation.

The Republican, who took office 18 months ago, has made no secret that he has struggled with a weight problem.
