Erika Kirk, widow of conservative leader Charlie Kirk, paid tribute to her late husband on Friday by posting a heartwarming video of him teaching their young daughter the basics of physics.In the video, which had already amassed more than 2.1 million likes by Friday evening, Charlie Kirk sits at a table with their daughter, playfully explaining Isaac Newton’s three laws of motion using her sippy cup and a pair of sunglasses.Erika Kirk captioned the Instagram post: “My favorite memories will forever be us raising our babies together. I love you [Charlie Kirk]. Tell Sir Isaac Newton that GG is ready for her quiz.”The video shows Kirk walking through Newton’s principles: an object at rest stays at rest, every action has an equal and opposite reaction and force equals mass times acceleration. He jokes with his daughter as she prepares to drop her cup: “Okay, see, that’s the issue — you keep thinking when you drop [your sippy cup], it comes back up, but it doesn’t, okay?”Netizens responded to the video with an outpouring of support and prayers for Erika Kirk and her family. One user wrote, “This is beyond adorable, still praying for you continually.” Another added, “Erika, thank you for sharing these videos. Love you and praying for you. You are in my thoughts!”Charlie Kirk, 31, founder of Turning Point USA was fatally shot during a public debate at Utah Valley University on September 10. Tyler Robinson, 22, was arrested shortly afterward and faces charges of aggravated murder, with prosecutors seeking the death penalty.Since the tragedy, Erika Kirk has emerged as a prominent leader, delivering her first public speech promising to carry forward her husband’s mission. She condemned the violence, warning that those responsible had ignited an “unstoppable force” committed to advancing Charlie Kirk’s vision. She also expressed gratitude to law enforcement and Turning Point USA for their support, emphasizing that Charlie’s legacy would endure.In the aftermath, Erika Kirk was unanimously elected CEO and Chair of the Board of Turning Point USA, fulfilling her late husband’s wish for her to succeed him. Under her leadership, the organization has seen a surge in student sign-ups and engagement, signaling a continuation of Kirk’s conservative movement.
