What’s next from the president of the United States? Will he tell his critics that their “mother wears combat boots”?

Donald Trump went on another Twitter tirade today, telling four progressive members of the U.S. House of Representatives to go back to where they came from. He wrote on Twitter: “Why don’t they go back and help fix the totally broken and crime-infested places from which they came.”

Oh, wait! Except that only one of them — Rep. Ilhan Omar, D-Minn. — was born in a faraway land. She emigrated here from Somalia. She became a naturalized citizen, ran for Congress and then won. Oh, and she then took an oath to defend the Constitution of the United States. The other three, Reps. Alexandria Ocasio-Cortez of New York, Rashida Tlaib of Michigan and Ayanna Pressley of Massachusetts all are native-born Americans.

Gosh, do you think Trump’s tirade has anything to do with the fact that two of the congresswomen are black, one is Hispanic and one is of Middle Eastern descent?

I, too, have been critical at times of the overexposure some of these congressional rookies have gotten. However, for the president to blurt out that sophomoric, childish, petulant response reveals — as if we haven’t seen it already — a seedy side of what passes for his character.

The progressive congresswoman have become known as The Squad. They are making a good bit of news these days in their open challenge of House Speaker Nancy Pelosi’s leadership of the lower legislative chamber. They want Pelosi to fast-track impeachment of Trump; Pelosi keeps hitting the brakes.

Now we have the president turning this battle into something seriously ugly and despicable.
