Former US President Barack Obama has warned of a political crisis of the sort that we haven't seen before in light of the shocking killing of Charlie Kirk, a conservative activist and close ally of former President Donald Trump.

Speaking at an event in Pennsylvania, Obama stated that while he did not personally know Kirk and disagreed with many of his views, he described the murder as a horrific and a tragedy.

Obama criticized Trump's frequent derogatory remarks aimed at his political opponents, contrasting them with former Republican presidents who fostered national unity during tumultuous times. Responding to his comments, the White House described Obama as the architect of modern political division, reflecting the passionate partisan climate.

Kirk, 31, was shot and killed on September 10 during an event at Utah Valley University. Following the incident, Tyler Robinson, 22, has been charged with his murder and other crimes, with prosecutors seeking the death penalty, citing that Robinson had allegedly expressed justified reasons for his actions through text messages.

In the past week, various discussions surrounding the language of political discourse have emerged, with U.S. Attorney General Pam Bondi and Vice-President JD Vance calling for accountability against those who allegedly celebrated or condoned Kirk's death.

During his remarks in Erie, Obama emphasized the need for leaders to help unify the country during periods of high tension, urging Americans to respect differing viewpoints. He recognized the constructive approach of Utah Governor Spencer Cox, who navigated disagreements while maintaining a code of civil discourse.

Obama noted historical moments where leaders like President George W. Bush chose to foster unity after national tragedies, highlighting how starkly different current political rhetoric has become.

As tensions rise, public sentiments across both sides of the political spectrum continue to shape responses to this shocking incident, indicating the challenges that lie ahead for America's political landscape.
