New Jersey Gov. Chris Christie's (R) test results came back normal and he expects to leave the hospital later on Thursday, a spokesman said.
"He’s in the hospital in an emergency room, his wife and brother are there. He went through what would be called the [normal] battery of tests dealing with shortness of breath," Chrstie spokesman Michael Drewniak told The Hill.
"All tests came back negative, Drewniak continued. "That includes EKG, the initial bloodwork and a chest X-ray. This would appear to be at this stage this would be related to complications associated with his asthma."
Christie underwent the tests after he began having trouble breathing earlier Thursday.
Christie Chief of Staff Maria Comella said to The Associated Press that EKG, blood work and chest X-ray tests all came back normal on the governor.
Christie reportedly expects to leave Somerset Medical Center Thursday night.
Christie, 48, was sent to the hospital “out of an abundance of caution,” spokesman Michael Drewniak told The Star-Ledger of Newark, N.J.
“In line with someone dealing with asthma, he is being given routine tests as a precautionary measure,” his office said in a statement, according to wnyc.org. “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.”
Christie, who took office in early 2010 after beating then-New Jersey Gov. Jon Corzine (D), is widely considered a rising star in the GOP and has been mentioned both as a potential 2012 presidential candidate and a top prospect for the vice presidential ticket. Christie repeatedly has said he has no interest in running for either office in 2012.
GOP 2012 presidential candidate and former Massachusetts Gov. Mitt Romney has reportedly mentioned Christie as a strong candidate for the second spot, should he win the nomination.
Christie often has mentioned his asthma at town halls. He has also said he’s working at controlling his weight, in part by working out three times a week with a trainer.
“Slowly but surely, I’m taking the weight off,” he said.
