On Wednesday, the Washington Post reported that Special Counsel Robert Mueller is investigating whether President Trump obstructed justice following his firing of FBI Director James Comey, who was probing possible collusion between the Trump campaign and Russia. President Trump launched a bitter attack on Twitter Thursday, calling Mueller's investigation "the single greatest witch hunt in American political history." We discuss the scope and status of the investigation, what constitutes obstruction of justice and how any potential charges might be brought against the office of the president.
