Senate Minority Leader Mitch McConnell has experienced freezing episodes and difficulty answering questions at press events, with aides having to assist him. Experts believe these episodes may be related to injuries McConnell sustained earlier in the year, including a concussion and fractured rib. Medical experts suggest that the freezing episodes may be connected to McConnell's falls and could be symptoms of a traumatic brain injury, Parkinson's disease, or another condition. There is speculation that McConnell may be considering retirement if he is in the advanced stages of an illness.
