It's Time for Congress to Open an Impeachment Inquiry
Now that Robert Mueller has spoken, it's time for Congress to open an impeachment inquiry into President Trump's conduct. To be clear, we are not calling for President Trump's impeachment - we're calling on Congress to do its job, investigate whether the President committed high crimes & misdemeanors when attempting to obstruct the investigation into Russia's attack on the United States' democracy with "information warfare." As Mueller has now clarified, only Congress is endowed with the power to investigate and hold the President responsible for crimes committed while in office.
Why Must Congress Act?
Congress needs to open an impeachment inquiry for two very important reasons: first, because our national security is threatened, and second, because in the United States, no man is above the law!
Despite the President's claims that the Mueller Report concluded that there was "No collusion, no obstruction," on the part of the President, in reality the Report described the most serious attack on our nation by a hostile foreign power since 9/11, and documented 10 different incidents in which President Trump attempted to obstruct the investigation of that attack.
Regardless of whether or not there was a full-blown conspiracy between Donald Trump (and/or his campaign) and the Russian government, the simple fact of the matter is that Russia helped Donald Trump to win the 2016 Presidential Election. Not only does this permanently taint the legitimacy of Donald Trump's presidency, it raises serious questions about whether a hostile foreign power might have leverage or undo influence over the American President.
No Man Is Above The Law
The second major reason that Congress must open an impeachment inquiry into President Trump is that one of the guiding principles of our Constitutional Republic is the notion that no man is above the law. Unlike any other person in the United States, the American President cannot be indicted while in office (footnote links to DOJ OLC opinion). However, the DOJ OLC opinion that provides the basis for this interpretation of the law does not mean that the President is above the law. On the contrary, our Constitution provides a specific tool and process for addressing a President who has allegedly engaged in criminal acts, and that's impeachment.
Whereas any other person in the United States would be subject to arrest and/or indictment, and have their day in court to defend themselves against the crimes they've been charged with, in the case of the American President, the U.S. House of Representatives bears responsibility for investigating any alleged crimes, and the U.S. Senate bears responsibility for trying the President and determining whether or not he is guilty of committing said crimes.
In the case at hand, the Mueller Report did not exonerate the President of wrongdoing. On the contrary, it documented a list of 10 separate incidents in which the American President attempted to obstruct justice, but explained that since the DOJ OLC policy held that a sitting President can't be indicted, responsibility for investigating and prosecuting any alleged crimes was the responsibility of the U.S. Congress.
However, since the Mueller Report was released, the U.S. Congress has failed to open an impeachment inquiry into the President's alleged offenses, despite the overwhelming evidence that suggests such an investigation would be the proper course of action.
