Am I able to make a presumption without sounding presumptuous?

I’ll give it a shot.

Robert Mueller, the special counsel assigned to examine Russian meddling in our 2016 election, reportedly has just impaneled a grand jury to begin hearing evidence and, more than likely, call witnesses to tell the panel what they know about this matter.

Here’s my presumption: I am going to presume that Mueller’s investigation is gaining some speed and that the former FBI director just might be smelling some blood in the water around Donald J. Trump and his presidential campaign team.

Recall for a moment another grand jury that a special counsel impaneled. I refer to the panel called into duty at the behest of Kenneth Starr, who was ostensibly examining a real estate transaction involving Bill and Hillary Clinton. Then he stumbled onto something quite unexpected: a relationship that President Clinton was having with a young White House intern. He summoned the president to testify before the grand jury, which asked him about that relationship. The president didn’t tell the truth.

Bingo! Impeachment followed.

Is the past going to be a prologue for what might await the current president?

As the Wall Street Journal reports: “Grand juries are powerful investigative tools that allow prosecutors to subpoena documents, put witnesses under oath and seek indictments, if there is evidence of a crime. Legal experts said that the decision by Mr. Mueller to impanel a grand jury suggests he believes he will need to subpoena records and take testimony from witnesses.”

I believe it also suggests that Mueller might expand his probe into areas other than precisely the Russian meddling and the allegations of collusion between the Russians and the Trump presidential campaign. There might be a subpoena or two coming that deals with, say, Trump’s tax returns and assorted business connections involving Trump’s business interests and Russian government officials.

Here’s another presumption: This story is still building.
