Republican Sen. Mitch McConnell of Kentucky on Sunday announced, after weeks of speculation, that he had a fall last month that landed him in the hospital.

“My doctors have confirmed that I didn’t break any bones or suffer a concussion. I didn’t have a heart attack or a stroke. I don’t have any tumors or hemorrhages. But I was briefly unconscious and was taken to the hospital. While receiving excellent care over the past several weeks, I’ve also had to deal with a mild case of pneumonia,” he said in a statement.

McConnell also provided a photo showing him smiling next to his wife, Elaine Chao. He appears to have a copy of Sunday’s Washington Post sports section on his lap.

McConnell said he’s moved from a hospital to a rehabilitation center to continue regaining his strength. His doctors have run through “every test they can think of” to try to determine what caused the incident.

The former Senate majority leader said he “won’t be able to return to the Senate floor to vote quite yet” but he’s “been working closely” with legislative staff in the meantime.
