Sen. Chris Van Hollen suffered a minor stroke

Maryland Sen. Chris Van Hollen said Sunday that he had suffered and received treatment for a minor stroke but will return to work in the Senate later this week.

"Earlier today, an angiogram indicated that I had experienced a minor stroke in the form of a small venous tear at the back of my head."In a statement, the 63-year-old Democrat senator said.

"Fortunately, I have been informed that there are no long-term effects or damage as a result of this incident, but my doctors have advised that out of an abundance of caution, I remain under observation for a few days."

After experiencing lightheadedness and sharp neck pain while delivering a speech, Van Hollen was admitted to the George Washington University Hospital, where he will remain for a few days.

"I look forward to returning to work in the Senate later this week and thank the medical team for their excellent care," he also said.
