Senate Minority Leader Mitch McConnell appeared to freeze for about 30 seconds on Wednesday while speaking with reporters after a speech in Covington, Kentucky.

The incident is similar to an episode McConnell experienced at the US Capitol late last month and is likely to raise additional questions about the fitness of the 81-year-old to lead the Senate Republican caucus.

Wednesday's episode occurred when a reporter asked the Republican leader if he was planning to run for reelection in 2026. McConnell had to ask him to repeat the question several times, chuckled for a moment, and then paused.

Someone at his side then asked him, "Did you hear the question, senator, running for reelection in 2026?" McConnell did not respond.

"I'm sorry you all, we're gonna need a minute," the aide told reporters. A member of the senator's detail spoke quietly to him for a moment, and McConnell was able to whisper an answer to him.

McConnell turned back to reporters, said, "OK," and his aide asked if anyone had another question, and if reporters could "speak up."

CNN has reached out to McConnell's office for comment.

McConnell, the leader of the Senate Republican caucus since 2007, has faced questions about his health throughout the year. He was treated for a concussion and fractured rib after falling at a hotel in Washington in March, returning to the Senate several weeks later.

In late July, McConnell froze for 30 seconds during a news conference on Capitol Hill. At the time, his office said the Kentucky Republican was "lightheaded" and Republicans later said that he was dehydrated. Speaking to reporters after the incident, McConnell insisted he was "fine."

White House press secretary Karine Jean-Pierre wouldn't say early Wednesday afternoon if President Joe Biden was aware of McConnell's latest freeze but said "clearly, we wish him well -- a speedy recovery."
