Washington, D.C. has been rocked by the sudden passing of Senator Lindsey Graham (R-S.C.), whose unexpected death on Saturday night sent shockwaves through the nation's capital. New details emerging from emergency dispatch audio paint a poignant picture of the frantic moments leading up to the announcement, even as President Donald Trump honored the longtime lawmaker as a "true American Patriot."

Fox News Digital reviewed emergency dispatch audio capturing the urgent response to Senator Graham's Washington, D.C., home. The initial dispatch, shortly after 8 p.m. local time, reported a cardiac arrest. As first responders raced to the scene, dispatchers relayed that the caller indicated the front door was unlocked.

However, upon arrival, emergency crews found the door locked with no response from inside. Metropolitan Police Department officers were immediately requested to force entry, underscoring the gravity of the situation unfolding.

Within 20 to 25 minutes of the initial dispatch, radio traffic confirmed that CPR was in progress as emergency teams worked inside the senator's residence. While the audio did not identify Graham by name, it provided a glimpse into the intense efforts to save him. Authorities later declared the incident a "Capitol Police matter only," a protocol often reserved for high-profile figures.

The final relevant radio traffic concluded shortly after 9:30 p.m., leaving many questions about the full extent of the responders' findings and the specific medical care provided. Graham's office later issued a statement confirming the 71-year-old senator had passed away Saturday evening after a "brief and sudden" illness.

"On the evening of Saturday, July 11, U.S. Senator Lindsey Graham passed away from a brief and sudden illness," his office stated. "Senator Graham's family appreciates prayers at this time and asks for privacy during this incredibly difficult period."

The Office of the Chief Medical Examiner for the District of Columbia provided preliminary findings on Sunday, indicating Graham died from an aortic dissection due to arteriosclerotic cardiovascular disease. Officials noted that the final death certificate would remain pending until all toxicological and microscopic testing is complete.

President Donald Trump, a key ally, offered a heartfelt tribute to Graham on Truth Social Saturday night, recognizing him as "a true American Patriot."

"Senator Lindsey Graham, one of the greatest people and Senators I have ever known, is dead!" Trump wrote. "He was always working, and was a true American Patriot. Lindsey will be greatly missed!!! DETAILS AND ARRANGEMENTS TO FOLLOW. So sad!"

Graham's distinguished career included four terms in the U.S. House of Representatives before his election to the U.S. Senate in 2002. He was serving his fourth term and had just won the Republican primary last month, setting the stage for a bid for a fifth Senate term. His extensive service also included 33 years in the U.S. Air Force, Air National Guard, and Air Force Reserve, where he retired as a colonel in 2015, with active duty during the Gulf War and multiple deployments to Iraq and Afghanistan.

Just a day before his passing, Senator Graham had met with Ukrainian President Volodymyr Zelenskyy in Kyiv and was scheduled for an appearance on NBC's "Meet the Press" Sunday morning, highlighting his active role in global affairs until the very end. His passing marks the end of an era of dedicated public service, leaving a void in the conservative movement and the halls of Congress.
