  1. Susan Giarrusso Reply

    Shame on you…nary a mention of her radical liberal biases, including peddling the false Russian narrative. She’s just another nobody who only became “relevant” because of CNN’s absurd focus and manufacturing of false tales during President Trump’s administration.

    • I’d wear that “critique” with honor. It reflects her strong “reality” bias, not the fake reality invented to make money for the fascists of the Fox universe.

  2. Susan Giarrusso, you nailed it. Her reward for lying about Trump and conspiring in the Russia hoax is a senior position in Biden’s Justice Department. There she can help restore the corruption that began under Obama. Look for her to lead Garland’s efforts to kill the Durham investigation.
