President Trump’s ongoing War on Grammar provides teachable moments — at least those displayed in tweets.

The latest example involved a mangled modifier — disseminated overnight — in which the commander in chief said: “Republicans Senators are working hard to get their failed ObamaCare replacement approved. I will be at my desk, pen in hand!”
Trump meant to say the opposite — that Republican senators were working hard to get enough votes for their replacement of “failed ObamaCare.”
Republicans Senators are working hard to get their failed ObamaCare replacement approved. I will be at my desk, pen in hand!

One Twitter account event specializes in Trump miscues.
The president’s syntax, spelling and punctuation errors are well-documented (and sometimes self-deleted).
Polly Higgins wrote on AM New York: “Though President Donald Trump may not be a ‘polished politician,’… he is a longtime English speaker. And yet the gaffes, the offenses made to those who support proper use of the English language, are many.”
In 2016, Trump tweeted: “Looks to me like the Bernie people will fight. If not, there blood, sweat, and tears was a total waist of time. Kaine stands for opposite!”
He deleted the “waist/there” version for a “waste/their” fix in July 2016.
Will he tweak his latest tweet?
