U.S. Sen. Mitch McConnell says he won’t return to the Senate “yet” after suffering a fall and “a mild case of pneumonia.”

It is the first statement from the 84-year-old Kentucky Republican after weeks of speculation about his health, following his admission to the hospital in mid-June.

His office released a photo in addition to the statement showing McConnell with his wife holding what appeared to be Sunday’s Washington Post newspaper.

He said he was “briefly unconscious” after his fall and was taken to hospital, where he “underwent every test they could imagine to help find out what caused this incident.”

“My doctors have confirmed that I did not break any bones or suffer a concussion. I did not have a heart attack or stroke. I have no tumors or hemorrhages,” he said.

Addressing his tremendous speculation about the absence, McConnell said, “People of my generation are often hesitant to share the vulnerability that comes with aging.”

He also referenced the polio he suffered in his childhood and the ongoing “mobility challenges” he faces as a result, saying, “They haven’t gotten any easier to manage with age. And last month, I suffered a fall that put me in the hospital.”

McConnell contracted polio at the age of two, which left part of his left leg paralyzed. He has credited extensive physical rehabilitation and a protective mother for ensuring he was able to walk again.

In addition to facing the remnants of his polio diagnosis, the senator said he faced a mild case of pneumonia while in the hospital.

He has now been transferred from the hospital to a rehabilitation center, according to the statement.

“You all know that people of my generation are often hesitant to share the vulnerability that comes with aging,” the statement said.

“As much as I am frustrated, this process takes time. And on the advice of my doctors, I will not yet be able to return to the Senate floor to vote.”

“Even in front of the public I feel the same instinct: I can’t help it.”
