D.C. Council member Marion Barry (D-Ward 8) suffered a blood clot while traveling to Las Vegas for an annual retail convention, according to tweets on his official account Sunday night.

”Got a blood clot while waiting on plane in Memphis,” said a tweet posted shortly before 8 p.m. Eastern time. “Taking blood thiner. I thank God it was caught.”

Neither Barry, 76, nor his chief of staff immediately returned calls or e-mails Monday morning. WRC-TV reported Monday morning that Barry was taken to Summerlin Hospital Medical Center; it is unclear whether he remains admitted.

A subsequent tweet referenced a recent Barry controversy, when in a council hearing last month, he lamented a high number of immigrant nurses, particularly from the Philippines. But the tweet singled out the “kind professional Filipino staff” who treated him Sunday.

“I stand corrected; I truly didn’t mean 2 hurt or offend,” it read.

It’s not the first time Barry has been hospitalized while traveling on official business. He was famously admitted to a Los Angeles hospital in 1987 while on a Super Bowl trip. It was one of Barry’s most high-profile health issues in a public career full of them. Most recently, he underwent urinary tract surgery in January.

The 2001 death of a 28-year-old British woman on a long international flight brought great attention to the heightened risk of blood clots during air travel.A 2007 World Health Organization study found that the risk of clotting roughly doubles after four hours of travel.

UPDATE, 11:10 A.M.: A tweet this morning indicated that Barry has been cleared to leave the hospital: “Just met w/the hematologist who said I can leave, but have 2 stay on blood thinners, exercise everyday &on plane, take it easy next few days.”
