In her first show since Barr’s memo was released, Maddow barely mentioned collusion.

Instead, she focused skeptically on Barr’s brief summary of Mueller’s findings, questioning why the attorney general, a Trump appointee, had decided there was insufficient evidence to make an obstruction accusation against Trump despite Mueller’s reluctance to make the same determination.

She demanded the release of Mueller’s full report and underlying evidence, an idea the House endorsed unanimously earlier this month. She also raised 15 questions about Barr’s conduct, including the last, “Will Trump recognize Russia attacked our election?”
