The assassination of right-wing activist Charlie Kirk has turbocharged the conversation — and fears — around political violence in the U.S. And, more than perhaps any other recent high-profile incident, it has fed claims that far-left extremists are primarily responsible for the worsening environment.

“From the attack on my life in Butler, Pennsylvania, last year, which killed a husband and father, to the attacks on ICE agents, to the vicious murder of a health care executive in the streets of New York, to the shooting of House Majority Leader Steve Scalise and three others, radical-left political violence has hurt too many innocent people and taken too many lives,” President Trump said, just hours after Kirk was killed.
