Senate Minority Leader Mitch McConnell has experienced multiple incidents of freezing or pausing during public appearances, prompting concerns about his health. McConnell's spokesperson attributed the pauses to feeling momentarily lightheaded, and President Biden expressed concern and plans to contact McConnell. McConnell has affirmed his commitment to serving his full term despite the concerns. These incidents have occurred after McConnell suffered a concussion from a fall in March. McConnell has been the top Senate Republican since 2007 and successfully defended his leadership position in November.
