WASHINGTON >> Senate Republican Leader Mitch McConnell briefly left his own press conference Wednesday after stopping his remarks mid-sentence and staring off into space for several seconds.

McConnell approached the podium for his weekly press conference and began speaking about the annual defense bill on the floor, which he said was proceeding with “good bipartisan cooperation.” But he then appeared to lose his train of thought, trailing off with a drawn-out “uh.”

The Kentucky senator then appeared to freeze up and stared vacantly for around 20 seconds before his colleagues in Republican leadership, who were standing behind him and could not see his face, grabbed his elbows and asked if he wanted to go back to his office.

He did not answer, but slowly walked back to his office with an aide and Wyoming Sen. John Barrasso, a former orthopedic surgeon who is the No. 3 Republican in the Senate. After sitting down in his office for several minutes, McConnell later returned to the press conference and answered questions from the press.

McConnell, 81, was out of the Senate for almost six weeks earlier this year after falling and hitting his head after a dinner event at a hotel. He was hospitalized for several days, and his office later said he suffered a concussion and fractured a rib. His speech has sounded more halting in recent weeks, prompting questions among some of his colleagues about his health.

When he returned to answer questions, McConnell said he was “fine.” Asked if he is still able to do his job, he said, “Yeah.”

McConnell’s office declined to say whether he was seen by a doctor following the episode.

After the press conference, Barrasso told reporters he “wanted to make sure everything was fine” and walked McConnell down the hall to his office.

Barrasso said he has been concerned since McConnell was injured earlier this year, “and I continue to be concerned.”

But asked about his particular concerns, Barrasso said: “I said I was concerned when he fell and hit his head a number of months ago and was hospitalized. And I think he’s made a remarkable recovery, he’s doing a great job leading our conference and was able to answer every question the press asked him today.”

Walking out of his office Wednesday evening, McConnell again told reporters he was fine. He said President Joe Biden had called him.

“The president called to check up on me, and I told him I got sandbagged,” McConnell joked, referencing a quote from Biden in June after he tripped over a sandbag and fell while onstage at the U.S. Air Force Academy graduation.

First elected to the Senate in 1984, McConnell became the longest-serving Senate party leader in history in January.
