First he went after the prosecutors who recommended a multiyear sentence for his friend Roger Stone. Then President Trump turned his Twitter ire to the “witch hunt disgrace” of special counsel Robert S. Mueller III’s investigation, which led to Stone’s indictment. But perhaps most surprising was Trump’s decision to target U.S. District Judge Amy Berman Jackson — who will determine Stone’s fate when he appears in her courtroom next Thursday.

House Judiciary Committee Chairman Jerrold Nadler accused Senate Republicans of violating their oath to be impartial jurors in an impeachment trial, as GOP senators defended their right to work for President Trump’s acquittal. Senators take an oath to “do impartial justice” at the start of any impeachment trial — but several Republican senators argued that impartiality doesn’t cover politics.

Special counsel Robert S. Mueller III reiterated Wednesday that his office could not clear President Trump of obstructing justice, asserting in his first public remarks about his investigation that federal prosecutors cannot accuse the commander in chief of a crime, while suggesting Congress still may do so.

The defining moment of Jeff Sessions's time as attorney general has been when he recused himself from oversight of the Russia investigation. That quickly led to the appointment of special counsel Robert S. Mueller III, who is now extensively probing President Trump. And by all accounts, it seriously strained Sessions's relationship with Trump, who thinks Sessions should  be protecting him and doing his bidding.
