I decided long ago that I wouldn’t lament Donald Trump’s use of Twitter as a policy bullhorn. I get that it works for the president, even though his tweets are so remarkably inarticulate, clumsy and, um, full of lies.

However, I cannot let pass a recent message he fired off while he is visiting the United Kingdom on a state visit at the invitation of Her Majesty Queen Elizabeth II.

At a time when the president should be exhibiting solemn respect for the office he holds and paving the way to pay his respects to the valiant warriors who fell in battle 75 years ago while trying to liberate Europe from the Nazi tyrant, he does something truly astonishing.

Donald Trump decides to engage in a Twitter battle with Bette Midler, the noted singer and actress.

Midler dislikes the president. She said so yet again. So what does the target of her barbs do? He decides to fire off a tweet in response to Midler, calling her a “washed up psycho,” or words to that effect.

Good ever-lovin’ grief, Mr. President!

Donald Trump is managing to make the presidency a worldwide laughingstock at a time when he should be conducting himself with maximum decorum and dignity.

A tweet tirade with Bette Midler isn’t the way to do that.

Weird.
