"In an interview with NBC on Sunday, Cox said Robinson "does come from a conservative family, but his ideology was very different than his family... There clearly was a leftist ideology with this assassin in recent years." He did not provide any further details."
Kimmel said that the shooter was clearly MAGA which is asinine based on evidence. I don't know what sources you are reading about Trump supporters, most I have encountered believe that he is Antifa and killed Kirk because of his leftist beliefs and Charlie's discussion of the Transgender issue as the shooter is living with a transitioning male partner. Did you see the texts that the shooter supposedly sent to his partner? I suggest you look that up.
