FBI agents returned to the late Sen. Lindsey Graham’s home in DC on Monday after the South Carolina Republican suddenly died due to a ruptured aorta two days prior.

Photos show at least five agents moving in and out of the Capitol Hill residence around 2:30 p.m. ET, with one carrying a clipboard and another wearing latex gloves.

Jerrett Wilson from Fort Lauderdale, who has been staying at a nearby Airbnb on vacation, told The Post: “Saturday night we were coming back from dinner about 9:30, and the street was shut down. Paramedics, law enforcement, and as we were walking up, they stopped us.”

“We told them where we were staying at. They let us go, and as we were walking up there, we saw the gurney being rolled out with somebody on,” he said.

“There’s just been heavy law enforcement presence today with the FBI. I want to say the ATF [Bureau of Alcohol, Tobacco, Firearms and Explosives] was out here as well, going in … the house and interviewing some neighbors,” he added.
