(CNN) - Sen. John Boozman, R-Arkansas, experienced an aortic aneurysm and underwent surgery Tuesday morning, according to a source familiar with the senator's condition.
The senator started feeling sick Monday night, and he and his wife canceled their plans, the source said. As his symptoms worsened, he went to the hospital, where the surgery appeared to be a success.
"So far, so good," said the source.
His office confirmed that he had surgery at an Arkansas hospital and is "receiving excellent care," but did not disclose any more information about the procedure.
Boozman was scheduled to have breakfast with mayors in Northwest Arkansas on Tuesday and was set to appear at a ribbon-cutting ceremony.
Senate Minority Leader Mitch McConnell issued a statement wishing his colleague well as he recovers from surgery.
"We’re glad to hear that John is doing well and we all look forward to having him back at work," the Kentucky Republican said.
"He is a fantastic Senator and a tireless advocate for Arkansas and the people he so proudly represents.”
