Here is a copy of the letter that Donald John Trump sent to former FBI Director James Comey informing him that he was being relieved of his duties immediately.

No expression of thanks for Comey’s service to nation is here. No salute for Comey’s work at the FBI or as U.S. attorney in New York state. All we get here is some expression of thanks that Comey told the president he wasn’t being investigated.

This stunning development, though, is crawling with back stories.

One of them involves why the president praised Comey so effusively on the eve of Election Day. Why did the president declare that Comey was such an excellent public servant after he sent that letter to Congress informing lawmakers of his intention to look yet again at those e-mails that Hillary Clinton sent out when she served as secretary of state. Back then Comey seemed to be a candidate for sainthood, the Nobel Prize and perhaps even a spot on Mount Rushmore.

Today, though, Comey’s name is mud. Trump reportedly is angry that Comey “wasn’t doing a good job.”

Oh, but wait. Now we hear that Comey sought more money and manpower to step up his investigation into whether Trump’s campaign colluded with Russian government officials who were hacking into our electoral system.

One more thing: We now hear that Trump was “thinking about” getting rid of Comey since right after the 2016 presidential election. Sure thing. Was the president also “thinking about” bungee jumping off the Washington Monument?

Senate Majority Leader Mitch McConnell said today he won’t appoint a special prosecutor.

Are we now expected to believe that Donald Trump is going to appoint someone to continue an investigation into his own administration and his own campaign and whether something improper occurred between Trump and a foreign power?

I believe the concerns coming from congressional Democrats and Republicans. They are labeling this controversy as a full-blown constitutional crisis.

We need an independent counsel to grab this investigation by the throat.
