I am running out of ways to express my dismay, disgust and disbelief at what I keep reading about the president’s Twitter tantrums.

Donald J. Trump launched another one, going after special counsel Robert Mueller’s team of investigators. He says they have gone “absolutely nuts.” He says Mueller, a former FBI director, is burden by a loads of conflicts of interest. He declares — falsely, if you’ll excuse me — that Mueller worked for President Obama for eight years; he worked for Obama for a couple of years after the new president asked him to stay on after President Bush (who hired him) left office in 2009.

It looks for all the world to me like classic “projection.” The president, not Mueller, has gone “absolutely nuts.”

Mueller is trying to finish his probe into “the Russia thing.” He has sent some of his lawyers home. Word is out that he and his team are drafting their final report. He has proceeded quietly, never saying a word publicly about what he knows, or where he has come up empty.

Meanwhile, the president continues to blast away with idiotic Twitter messages. He seeks to undermine an ongoing federal investigation. He disparages the Justice Department, the FBI, you name it.

Meanwhile, rather than focusing intently on preparing for the next Congress taking office in January — a body that will look quite different from the current Congress — Trump is busying himself with these goofy Twitter tirades.

The president needs to prepare a legislative agenda that should be considered by a House of Representatives controlled by Democrats. He needs to study the piles of reports his staff (presumably) has prepared for him. Oh, I forgot: He doesn’t read reports, being blessed — as he has said — with a brilliant mind.

OK. Let’s all get ready for the second half of the president’s term. If you thought the first half’s ride was bumpy, it will look like a journey across placid waters compared to what lies ahead.
