Attorney General William Barr criticized President Trump Thursday, saying Trump’s tweets about the case of his longtime friend and former campaign adviser Roger Stone are making it impossible for Barr to do his job. This is Barr in an interview with ABC.

Attorney General William Barr: “To have public statements and tweets made about the department, about our people in the department, our men and women here, about cases pending in the department and about judges before whom we have cases, make it impossible for me to do my job and to assure the courts and the prosecutors and the department that we’re doing our work with integrity.”

Earlier this week, Barr intervened in Stone’s case after Trump went on a late-night Twitter rampage attacking federal prosecutors and calling the initial sentence of seven to nine years a “miscarriage of justice.” Four federal prosecutors withdrew from the Stone case, and one resigned from his job entirely, over the intervention. Democratic lawmakers are criticizing Attorney General Barr, with House Speaker Nancy Pelosi calling him one of Trump’s “henchmen” and Connecticut Senator Richard Blumenthal calling on Barr to resign.
