This from Reuters:

While there was no immediate word on the condition of the 59-year-old senator, the source, who is familiar with Johnson’s situation, said surgeons sought to remedy an unspecified medical problem.

Just hours after Johnson was admitted to George Washington University Hospital, a spokeswoman for him said the senator had not suffered a stroke. She provided no other details.

In a statement later, Johnson’s communications director Julianne Fisher said: “Senator Johnson continues to undergo testing and procedures at George Washington University Hospital. We expect to have more information in the morning.”

Again, I hope he’s okay.
