Greensboro Congressman Howard Coble, a Republican, was admitted to a Washington hospital Tuesday after a persistent respiratory illness.
Doctors at George Washington University Hospital found Coble's sodium levels were too low and admitted him for treatment, according to a statement from the congressman's office.
"His cold seemed much worse when he arrived in Washington last night,” said Ed McDonald, his chief of staff, in a statement. "He requested a leave of absence on Monday because he did not feel well enough to vote after his flight to D.C. was postponed by more than six hours yesterday in Greensboro. When he did not feel any better today, he visited the Attending Physician in the Capitol, who made the determination to transport Congressman Coble to George Washington University Hospital for observation."
His hospital visit could last four to five days. Coble aides said doctors have not detected any other health concerns related to the respiratory illness.
