Former US President Barack Obama has warned of a political crisis of the sort that we haven't seen before in the wake of the killing of Charlie Kirk. At an event in Pennsylvania on Tuesday, Obama said he did not know Kirk and disagreed with many of his views, but described the killing as horrific and a tragedy. He held up former Republican presidents who emphasized national unity during times of tension, juxtaposing their approach with the divisive comments made by Donald Trump and his allies.

Kirk, 31, was fatally shot while speaking at Utah Valley University on September 10. Tyler Robinson, 22, has been charged with Kirk's murder, and prosecutors plan to seek the death penalty. The president defended the necessity for political leaders to unify the country, especially in tumultuous moments, and called for respect in public discourse, even in disagreement.

Obama also applauded the responses from conservative and liberal leaders in the face of adversity and voiced criticism for those who fuel further division. In a pointed remark, he noted the difference in leadership styles between himself and Trump, emphasizing a need for empathy and constructive dialogue in American politics.
