The world, especially the USA, was shocked by the assassination of Republican and Christian figure Charlie Kirk on Wednesday. People around the globe joined in mourning the death of Turning Point USA's founder.Pundits and experts from many domains weighed in on the tragedy, from the political and business scenes to the sports scene. And on Thursday, OutKick founder Clay Travis posted a video of CBS Morning's panel discussing the incident in Utah.He highlighted former NFL wide receiver Nate Burleson's take. While Burleson aligned with the whole event being a tragedy, he urged people to reflect on their political perceptions and views."This is not a time to focus on [what people thought of Kirk's views]," Burleson said. "We're focused on this tragedy. Speaking of this tragedy, is this a moment for your party to reflect on political violence? Is it a moment for us to think of the responsibility of our political leaders and their voices, and what it does to the masses?"Travis didn't take kindly to Burleson's words. In posting the clip, he captioned it:"CBS News m*ron Nate Burleson says Republicans need to tone down their rhetoric after Charlie Kirk was assassinated at a free speech event."Given that Charlie Kirk was widely regarded as a polarizing figure, as Burleson also noted in his take, there were bound to be controversial takes. Nonetheless, most people still mourned the nature of his death.The NFL mourns Charlie Kirk's deathJust like in mainstream entertainment, many around the NFL also mourned Charlie Kirk's death. Kansas City Chiefs kicker Harrison Butker wrote:"Thank you for your strong witness for Christ @charliekirk11. Thank you for pursuing truth and leading your family as a husband and father. Eternal rest grant unto them, O Lord, and let perpetual light shine upon them. May their soul and the souls of all the faithful departed, through the mercy of God, rest in peace. Amen.”New York Giants rookie Jaxson Dart and Baltimore Ravens star Lamar Jackson also mourned Kirk's death.On the other hand, there were rumors that Minnesota Vikings star Justin Jefferson, Green Bay Packers quarterback Jordan Love and Philadelphia Eagles star Jalen Hurts offered considerable financial support to Kirk's family.
