Gov. Chris Christie has been hospitalized in a New Jersey Hospital after he had trouble breathing, his office said.
Christie was taken to Somerset Medical Center "out of an abundance of caution," spokesman Michael Drewniak told nj.com.
Drewniak said Christie has asthma and is "doing fine" and having more testing.
"In line with someone dealing with asthma, he is being given routine tests as a precautionary measure," Drewniak said.
"The governor is extremely grateful for the quality of care he is receiving this morning and has nothing but praise for the world-class doctors, nurses and staff,” he said.
Christie's history of asthma is no secret. He has made references to it during speeches, and has used himself as an example when discussing the merits of Obamacare.
Christie, who has frequently been mentioned as a possible Republican presidential candidate, is 48 and is heavily overweight. He has publicly acknowledged struggling with his weight.
The Republican governor has said repeatedly that he is not running for the White House. Earlier this month former Massachusetts Governor Mitt Romney said Christie said was on his short-list for vice president if Romney wins the Republican Party's presidential nomination.
Christie has been a rising Republican star since taking office last year with a low-tax, lean-government agenda, and erasing a record $11 billion budget deficit while limiting annual increases in the state's high property taxes.
