WASHINGTON (AP) — Republican Sen. Mitch McConnell of Kentucky returned to the Senate on Monday for the first time since June 14, when he was hospitalized after a fall in his home.

McConnell's three-month absence from the Senate generated a flood of criticism and online speculation, as the Kentucky senator initially remained quiet for weeks about his condition. The 84-year-old senator eventually disclosed that he had been “briefly unconscious” due to the fall and had also been treated for mild pneumonia in the hospital.

“My recovery has been a long and often frustrating process, and the lingering effects of childhood polio haven’t made it any easier," McConnell said in a statement Monday. “I’m still not quite back to 100%, but I’ve assured Leader Thune that, as I continue with physical therapy on the advice of my doctors, I will do my best to be present for tough votes when our Conference needs me.”

The concerns over McConnell’s absence highlighted increasing public concern about the age of lawmakers and their capacity to carry out their duties. Speculation about his condition grew so intense at one point that Kentucky’s Democratic Gov. Andy Beshear took the extraordinary step of issuing a public letter asking McConnell to update the public in a “transparent manner.”

McConnell’s absence was also felt over the summer as Republicans were unable to advance a farm bill out of committee. His return could give GOP leaders a needed vote as they try to advance legislation on cryptocurrency regulation and college sports.
