Let’s assume for a moment the very worst about Jared Kushner, son-in-law and senior adviser to Donald J. Trump.

The Washington Post is reporting that Kushner suggested to Russian government officials that the Trump transition team set up a secret line of communication between the Russian embassy to the United States and the Kremlin.

OK, to be completely fair — the story might not be true. My sense, though, is that it’s there is something significant happening to the Trump administration.

So, if the Post is correct and Kushner was able to secure a back-channel line between the Trump team and the Kremlin — using Russian communications equipment — how does that compare with what the Trump campaign alleged about Hillary Rodham Clinton’s use of her personal e-mail server?

Do you remember the chants of “Lock her up!” coming from those Trump campaign rallies? Do you recall that disgraced former Trump national security adviser Michael Flynn helped lead those chants himself?

What Kushner is reported to have sought makes Hillary’s use of personal e-mail accounts look so, so quaint.

Think of this. The Post is reporting that Kushner wanted to use Russian intelligence equipment to transmit communications between the Trump team and the highest level of government in Moscow. Did this young man have a clue that Russians monitor carefully all communications between their embassies and the Kremlin?

I guess we now can understand a good bit more clearly why the FBI had declared Kushner to be a “person of interest” in its investigation of what the president called “the Russia thing.”

The Russia thing is growing a lot of legs.
