Councilmember Marion Barry tweeted from the hospital that he was being kept in a hospital overnight for observation.
D.C. Councilmember Marion Barry was taken to the hospital last night after he says he experienced a drop in blood sugar.
The longtime council member and former mayor broke the news from the hospital via Twitter.
Barry's chief of staff says he 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.
