OK, let’s take a quick look at a sequence of some troubling events.

* Donald J. Trump takes the oath of office as president of the United States.

* Twenty-four days later, he fires his national security adviser, Michael Flynn, because Flynn supposedly lied to the vice president about conversations he had with Russian government officials.

* The FBI starts looking at Flynn’s involvement with Russia.

* The president and FBI Director James Comey meet to discuss various matters and Trump then — allegedly — asks Comey to stop the investigation into Flynn, whom Trump describes as “a good guy.”

* Comey doesn’t do as Trump asks.

* Trump fires Comey as FBI director because, according to the president, he was spending too much time on the “Russia thing.”

Let me think. Does that sound like an obstruction of justice? It does to me.

I believe, dear reader, we just might have an impeachable offense on our hands.
