SEN. RICHARD BLUMENTHAL (D-CT): I hope my Republican colleagues in the U.S. Senate will take the lead on this issue and also on obstruction of justice. There is a credible case of obstruction of justice against Donald Trump If you take the President's own statement, his tweet that he knew Michael Flynn was lying to the FBI when he fired him, which means that he knew Michael Flynn committed a felony when he asked Comey to stop the investigation of him, and when he fired Comey when he refused to do so, and when he fired Sally Yates and when he called Michael Flynn in April to tell him to stay strong, all of these acts are to impede and obstruct justice.
