She’s done this before - denying she said something by fixating on a specific phrase that wasn’t attributed to her, and which everyone understood was a summation of her remarks, as if she could magic away what she actually said. I’m sure it works for her supporters, but she could just lie about it, too, for the same effect (although I guess she’s also done that).
I feel like she’s maybe angry because her carefully constructed dog whistles got ignored in favor of the content of her message. She probably felt really clever crafting that long a message about a Jewish conspiracy involving space lasers without actually using the words “Jewish conspiracy” or “space laser,” and someone just went straight to the incredibly dumb heart of what she was saying.
