Congressional Democrats are making a reasonable demand of the Trump administration, which is to strip White House adviser Jared Kushner of his top-secret security clearance … at least for the time being.

It’s not a simple task, of course. Kushner happens to be the son-in-law to the president of the United States. He’s also under “scrutiny” by the FBI, which is conducting a wide-ranging investigation into I’ve grown fond of calling the “Russia thing.”

That “thing” involves potential contact between the Trump presidential campaign and the Russian government. Kushner happens to be a principal actor in all that drama.

Trump hired him to be a senior adviser. Kushner doesn’t get paid but he has unfettered access to the president. He does not have any prior government experience. He has zero credentials to deal with foreign government leaders, yet the president considers him “qualified” to be a liaison between the administration and governments in the Middle East.

He’s also known to be a successful businessman. He’s had plenty of exposure to Russian business executive and government officials. Has he crossed any lines that might pose serious trouble for his father-in-law? That’s what the FBI is investigating.

Until the FBI reaches its conclusion, and if that conclusion clears Kushner, he has no business sitting at the president’s side during high-level meetings. He shouldn’t be privy to information reserved for the president and his national security team.

Let’s allow the FBI probe to continue. If the young man skates into the clear, fine. If not … well, then we’ve got a whole set of other problems with which to deal.

Until then, Kushner should be sitting at the kids’ table — in another room away from where national secrets are being discussed.
