Washington DC - Connecticut Representative John Larson froze during an impassioned speech on the House floor in yet another concerning health incident.

The 76-year-old congressman was in the middle of a passionate speech about the social security and President Donald Trump, before stuttering and freezing mid-sentence.

After standing in silence for about 20 seconds, he attempted to continue, but was only able to speak slowly with long pauses.

Amid concern following the incident, representatives for Democrat told the Connecticut Mirror that he had suffered an adverse reaction to some new medication and is undergoing further medical tests.

"He later participated in multiple meetings in his office and was alert and engaged," the statement said.

"Congressman Larson appreciates the well wishes from everyone who has reached out. The Congressman remains in touch with his staff and in good spirits."

The episode was reminiscent of the scares suffered in 2023 by Senate Majority Leader Mitch McConnell, who on multiple occasions he froze at the lectern while taking questions from the press.

Concerns about the health of elected representatives has grown in recent years, with the current Congress being the third-oldest in US history.
