President Trump called the assassination of Turning Point USA founder Charlie Kirk a “dark moment for America,” in a message from the Oval Office Wednesday night. 

“To my great fellow Americans, I am filled with grief and anger at the heinous assassination of Charlie Kirk on a college campus in Utah,” Trump said in a four-minute video posted on Truth Social.

“Charlie inspired millions. And tonight, all who knew him and loved him are united in shock and horror,” the president, seated behind the Resolute desk, continued. 

Trump said the slain 31-year-old conservative activist is now a “martyr for truth and freedom.” 

“This is a dark moment for America,” the president added.

Trump blasted the “radical left” for comparing “wonderful Americans like Charlie to Nazis and the world’s worst mass murderers and criminals.” 

“This kind of rhetoric is directly responsible for the terrorism that we’re seeing in our country today, and it must stop right now,” Trump declared. 

Trump vowed that his administration will “find each and every one of those who contributed to this atrocity and to other political violence, including the organizations that funded and supported, as well as those who go after our judges, law enforcement officials, and everyone else who brings order to our country. 

“The monster who attacked him was attacking our whole country,” Trump charged. “An assassin tried to silence him with a bullet, but he failed because together we will ensure that his voice, his message and his legacy will live on for countless generations to come.”

Kirk was shot in the neck while hosting an event at Utah Valley University. 

The shooting occurred during the first stop of Kirk’s “American Comeback Tour” of campus speaking engagements.

Earlier Wednesday, Trump exclusively told The Post that the Turning Point USA founder was “not doing well.”

“It looks very bad,” the president said in a brief phone interview as the nation reeled from news of the shooting. “He was a very, very good friend of mine, and he was a tremendous person.”

“We must all pray for Charlie Kirk, who has been shot. A great guy from top to bottom. GOD BLESS HIM!” the president wrote on Truth Social after receiving initial word of the shooting at Utah Valley University.

Kirk was initially said to be in critical condition after he was hit with a single shot at the campus in Orem.

Vice President JD Vance tweeted shortly before Trump’s message was posted: “Say a prayer for Charlie Kirk, a genuinely good guy and a young father.”Kirk cofounded TPUSA in 2012 at age 18 after dropping out of Illinois’ Harper College — with the group rapidly emerging as a large national network of young conservatives, eclipsing the College Republicans in influence since Trump’s first election in 2016. 

At 4:40 p.m. ET, Trump announced that Kirk had died. 

“The Great, and even Legendary, Charlie Kirk, is dead,” the president wrote on Truth Social. “No one understood or had the Heart of the Youth in the United States of America better than Charlie.

“He was loved and admired by ALL, especially me, and now, he is no longer with us. Melania and my Sympathies go out to his beautiful wife Erika, and family. Charlie, we love you!”

In addition to leading the grassroots group, Kirk has served for years as a prominent pro-Trump surrogate and as an informal adviser to White House and Republican Party officials on messaging, policy and staffing. 

Former Rep. Jason Chaffetz (R-Utah), who attended the event with his daughter, said in a Fox News interview that a single shot rang out as Kirk was answering a question about transgender mass shooters.

The Utah college said in a statement that Kirk was shot by a gunman positioned inside a building about 200 yards from where Kirk was seated.

Video showed Kirk physically recoiling and falling out of his chair at the open-air event less than an hour south of Salt Lake City and near Provo’s private Brigham Young University. 

Utah Republican Gov. Spencer Cox said, “Those responsible will be held fully accountable. Violence has no place in our public life.”

Kirk is known for hosting energetic public dialogues, including with ideological adversaries such as Gov. Gavin Newsom (D-Calif.), with whom he appeared on an amiable podcast in March.

“The attack on Charlie Kirk is disgusting, vile, and reprehensible,” Newsom tweeted. “In the United States of America, we must reject political violence in EVERY form.”

South Bronx Rep. Ritchie Torres (D-NY) said in a statement: “The shooting of Charlie Kirk at a college event in Utah is an attack on our democracy. Political violence has no place in America, and we must show zero tolerance for it anywhere in our nation.”

Sen. John Fetterman (D-Pa.) wrote on X: “There is ZERO place in our great country for these horrendous acts of political violence. We must find a better way forward. May Charlie Kirk have a full and quick recovery.”

“We are closely monitoring reports of the tragic shooting involving Charlie Kirk at Utah Valley University,” FBI Director Kash Patel tweeted. “Our thoughts are with Charlie, his loved ones, and everyone affected. Agents will be on the scene quickly, and the FBI stands in full support of the ongoing response and investigation.”

The shooter was still at large as of 10:15 p.m. ET.
