"The Great, and even Legendary, Charlie Kirk, is dead. No one understood or had the Heart of the Youth in the United States of America better than Charlie," Trump wrote. "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!"

Dean Cain told Fox News Digital prior to his death, "I am absolutely heartbroken and praying for Charlie and his family. This will not have the desired effect. This will not intimidate nor stop people from speaking the truth."

Rob Schneider wrote on X at the time, "As we pray for our dear friend and brother in Christ, American Patriot, Father, Husband and son, Charlie Kirk, We know that our God is a loving God. And we must remember that vengeance is the Lord’s. Not ours."

He added the Bible verse, "Deuteronomy 32:35 ‘To me belongeth vengeance, and recompence; their foot shall slide in due time: for the day of their calamity is at hand, and the things that shall come upon them make haste.’ May Jesus Christ, our Lord and Savior bless and heal our brother Charlie, and give peace to his family and friends at this time."

Video posted from the event appeared to show Kirk being shot as he spoke to the crowd from under a white pop-up tent. After the shot, the crowd dispersed, with onlookers shouting, "Run, run, run!"

Charlie Sheen's history with substance abuse dates back decades.

Sheen, 60, reflected on his addiction journey and the way his famous family organized an intervention in the early '90s in the new Netflix documentary, "aka Charlie Sheen."

The "Two and a Half Men" actor recalled receiving an invitation to celebrate his father Martin Sheen's 50th birthday, only to arrive for his own intervention, which included a pep talk from Clint Eastwood.

"I get invited to my dad’s birthday party," Sheen said in the docuseries, per People magazine. 

"I think Mom called me: ‘Dad’s got things to do, so we have to do it early.’ She’s like, ‘We’re thinking 9:00.’ I’m like, ‘a.m.?’ She’s like, ‘Yeah.’"

The "Major League" actor remembered, "She brings me into the house, and I’m looking for balloons, a cake, funny hats … And as I come around the corner, I see the living room has this really expertly organized circle of people."

Sheen said the group was "a weird mix," and included his seventh-grade history teacher, yoga instructor, Rob Lowe, and his siblings.

His longtime friend, Sean Penn, did not participate. Penn said in the docuseries that he was "never involved with those interventions" due to his own personal struggles.

"I was not, you know, walking a perfect trail of my own in some regards," Penn said.

Sheen remembered staying mostly silent during the "emotional" day, where his friends and family read letters.

"There’s a lot to process," he said. "I’d kind of heard about these things, but never been this close to an intervention." Sheen requested time away from the group to think about going into treatment, but "they said, 'No. This is a decision we’ve made for you that has to happen today.'"

He added, "I was figuring, ‘If I just agree to this, just to get out of this situation, I can probably hatch a plan somewhere away from here.'"

Sheen was deep in thought on ways to avoid getting treatment until his dad walked out of his office and said, "There’s someone on the phone who wants to talk to you."

The "Platoon" star took the phone expecting a family member, and knew exactly who he was speaking to the second he heard the tone. 

"It’s a very recognizable, very globally familiar voice," he said. "It’s Clint."

He added, "[Clint] said something like, ‘You’ve got to get the train back on the tracks, kid … You’re worth saving.' It was really powerful. I thanked him, gave the phone back to Dad and said, 'All right, let’s go.'"

Sheen finally got clean in 2017. "You have to be willing," he told People magazine. "I keep a [mental list] of the worst, most shameful things I’ve done, and I can look at that in my head if I feel like having a drink."
