District of Columbia Councilmember Marion Barry is in the hospital after he says he experienced a drop in blood sugar.
The longtime councilmember and former mayor tweeted Tuesday night that he was going to the hospital. His chief of staff, Joyce Clements Smith, says Barry went to the hospital after he started feeling weak. Doctors kept him overnight for observation.
The 77-year-old Barry has been hospitalized more often in recent years.
In May 2012, he was taken to the hospital in Las Vegas. He said he had developed a blood clot while waiting on a plane heading to a retail convention. He was also hospitalized in January 2012 for a minor operation following a urinary tract infection.
