FBI Director Kash Patel said on Sunday his agency is assisting local authorities in Washington, D.C., after four-term Sen. Lindsey Graham (R-SC), a close ally of President Donald Trump, died Saturday night following a “brief and sudden illness.”

“The FBI is assisting local authorities and has made every necessary resource available,” Patel said in a statement Sunday morning. There is no indication foul play was involved in Graham’s death.
