A sitting US Senator suddenly dies.

I could only find one somewhat recent death of a Congressmember at home, Paul Gilmor. His death was ruled to be injuries from a fall down stairs. It isn't clear if the FBI was involved in the investigation, but local police did determine no evidence of foul play.

theories.

Zelensky poisoned him 🙄

Senator Graham's recent secret trip to Ukraine made him vulnerable to a Russian/Iranian assassination attempt.
