NEW: Tucker Carlson appears to defend Erika Kirk amid ongoing attacks from Candace Owens. “I never weigh in on [Charlie’s assassination] because I love his widow, Erika. And, you know, I'm sad to see so much of what's happened ever since.” “I will just say the responsibility for investigating crime goes to the civil authorities, in this case, the federal and state authorities. And so the internet is not in charge of investigating crimes.” Video: The National News.
