Let’s play out a certain scenario that’s being discussed in Washington, D.C. at the moment.

Donald J. Trump reportedly is considering whether to invoke executive privilege to block former FBI director James Comey from testifying before the U.S. Senate Intelligence Committee.

The White House isn’t saying what the president will do.

Trump fired Comey as FBI director while the FBI is in the midst of an investigation into whether the Trump presidential campaign colluded with Russians who were hacking into the 2016 presidential election.

Trump canned Comey suddenly.

The Justice Department has appointed a special counsel to lead the investigation.

If the president blocks Comey’s testimony, what are we supposed to presume? Might it be that Comey has something terribly damaging to tell senators — under oath — about whether the president obstructed justice by pressuring him to back off an investigation?

Inquiring minds might want to know. Don’t you think?
