Donald J. Trump Sr. has pressed his foot hard on the presidential petulance pedal.

He fired off a series of tweets today attacking Democratic U.S. Sen. Richard Blumenthal after Blumenthal appeared on TV over the weekend to criticize the Justice Department’s emphasis on rooting out leakers.

Did the president call into question the specifics of Blumenthal’s criticism? Oh, no. He attacked Blumenthal for a lie he told about serving “in Vietnam” when in fact the senator — a Marine Corps reservist — didn’t set foot in the country during the Vietnam War.

Let’s see. That story came out during the 2010 campaign for the Connecticut U.S. Senate seat that Blumenthal was contesting. He apologized for his mischaracterization. As one who actually did set foot in Vietnam during the war, I was appalled at the time that Blumenthal would say such a thing. I chastised him heavily for it.

But that was then. It’s over.

Here is what I wrote about it at the time:

However, since Trump did bring it up, I guess it’s OK to remind readers of this blog that young Donnie Trump didn’t exactly distinguish himself either during that period in our nation’s history.

He got a boatload of student and medical deferments to keep him away from the war. Trump did suggest during the 2016 campaign that his attendance at a military high school in New York was essentially the same thing as serving in the military. Umm. No. It’s not. Honest.

I read somewhere in the past few days that new White House chief of staff John Kelly might be able to bind up the president’s Twitter finger. I guess that hasn’t happened, at least not yet.

In the meantime, Donald Trump continues to demonstrate with startling effectiveness that he possesses the temperament of a child. To think this individual also has control of nuclear launch codes that could destroy the world.
