The president of the United States has lied with such recklessness since entering the political world, it’s becoming difficult to single out which lie has done the most damage.

I believe I should look at one lie that on the surface seems the least consequential, but which has produced the most serious consequence.

It was his pledge to stop tweeting once he became president.

Yep, Donald J. Trump made that pledge. I cannot remember when he did, but he did. He said he would be more “presidential” once he actually took the oath, settled into the big chair in the Oval Office and started signing executive orders to do the things he promised to do.

Has he kept that pledge? Hah! No.

What has been the result? It’s been pretty far-reaching. I’ll start with the most recent tweet, which he fired off more than a week ago early on one morning. It was where he said Barack Obama “wiretapped” his office at Trump Tower. He said his predecessor did it, that he broke the law, that he committed a felony. He called it a “fact.”

Trump’s tweet has ignited a firestorm. I mean, it’s a serious conflict in Washington, D.C. He has generated bipartisan criticism, although the volume has been much louder among Democrats than Republicans.

Is this Twitter tempest ever going to end? Is this how he’s going to conduct foreign and domestic policy, through the use of a social medium in which he makes statements without consulting his senior staff?

Didn’t this clown say he would surround himself with the “smartest people” in the history of humankind? If that is what he has done, why aren’t they telling this idiot to cease and desist with the Twitter nonsense? Maybe they are … and he’s not listening.

The liar in chief is out of control.

You want any more examples of how dangerous this behavior can become in a world fraught with serious peril? We are witnessing it as it is happening.
