Sen. Elizabeth Warren (D-Mass.) on Friday formalized her call for the resignation of Attorney General William Barr. Following up on her Wednesday insistence that Barr resign over his apparent interference in the criminal case against Roger Stone, Warren led eight other Democratic senators in a formal letter calling for Barr's departure. "We are writing to express our alarm about and opposition to the unethical political intervention" by Barr and the Justice Department in the case of President Trump's longtime adviser Roger Stone, the senators, including fellow 2020 candidate Sen. Bernie Sanders (I-Vt.) claim in their letter to Barr. Trump tweeted his opposition to the prison sentence federal prosecutors recommended for Stone. The DOJ stepped in to lighten the recommendation, though Barr insisted Trump's tweets had nothing to do with it.
