Donald J. Trump’s response to the scathing testimony from a fellow he demoted in the midst of an infectious disease pandemic speaks volumes to me.

Dr. Richard Bright is now a whistleblower who is reporting to Congress about what he believes are serious shortcomings in Trump’s response to the coronavirus pandemic. Bright once led the administration’s effort to search for a vaccine to fight the virus, but then questioned whether Trump was correct to push a drug with little known affect on the COVID-19 virus.

Trump got angry and pushed Bright aside, sent him to a midlevel post in the National Institutes of Health.

OK, so Trump responded Thursday to a question about Bright’s testimony. He said he doesn’t “know him; I’ve never met him.” He said he doesn’t “want to meet him” and that Bright sounds like a “disgruntled employee.”

Let’s ponder that response for just a moment.

If Donald Trump is telling the truth — and that is a highly dubious presumption — then he has just revealed to the world precisely why his pandemic response has been such a hideous failure to date. The man chosen to lead the vaccine research effort is unknown to the commander in chief who wants to be known as a “wartime president”?

Suppose, too, that Trump is lying, that he really has met Dr. Bright; that tells me plenty as well about Trump’s reliability, his leadership and his command of the situation.

Bright said the fight against the pandemic lacks a coordinated national effort. Gosh, who do you suppose should be providing that national coordination? Hey, I’ll take a stab at it: The responsibility belongs to the president of the United States.

He has failed!

As Bright told the congressional committee: “We’re in deep s**t.”
