Efforts to subvert, undermine, torpedo, derail and discredit the House of Representatives impeachment inquiry into Donald Trump’s presidency are shooting blanks.

The inquiry launched by a formerly reluctant House Speaker Nancy Pelosi are rooted in the belief among House Democrats that Trump has committed impeachable offenses. That he has violated his constitutional oath. That he has broken federal law. That he has besmirched and belittled the high office he occupies. That he has abused his power and that he has obstructed the pursuit of justice.

All of these matters are serious and all of them are being pursued legitimately.

They are not intended, as Republican critics have suggested, to “overturn” the results of the 2016 presidential election. Trump will be recorded forever as the victor in that campaign, given that he won enough Electoral College votes to take the oath of office.

It has been the revelations that are coming out now that have created this concern among congressional Democrats.

His seeking political favors from a foreign government; his search for political dirt on his opponents; his efforts to obstruct the investigation into whether he colluded with Russians in the 2016 campaign; his incessant lying about who he knows or doesn’t know with regard to the Ukrainian matter; his request that China and other foreign powers investigate political foes here at home.

These are serious matters even if the House were to consider them separately. Taken together, they amount to a huge body of evidence against the president.

Then we had that ridiculous effort to censure House Intelligence Committee Chairman Adam Schiff for reciting an obvious parody of the conversation Trump had with the Ukrainian president. They have bellowed that Schiff misrepresented what Trump said. Hello? Anyone listening to Schiff’s comments in real time knew in the moment that he was spoofing the president.

Donald Trump is likely to be impeached by the House. It might come before Thanksgiving. Then the Senate will conduct its trial. Senate Majority Leader Mitch McConnell doesn’t want to drag it out. He wants it disposed of sooner rather than later. He doesn’t want it to linger into the election year. I agree with the leader on that matter. Get it done quickly!

But as President Ford said when he took office on Aug. 9, 1974 after President Nixon quit in the midst of another scandal: “Our Constitution works.”

It did then. It is working now. Let the House do its job … just as the Constitution prescribes.
