Donald John Trump is at it again.

The president let a political rally crowd shout “Send her back!” when he invoked the name of a progressive congresswoman who he attacked via Twitter.

Then he said he disagreed with the chant of his avid/rabid followers.

Oh, and then he said he agreed with them.

Now he is calling on the congresswoman and her three ultra-liberal colleagues to “apologize” to the nation for the “horrible things” they have said about the country and, oh yes, about his policies.

Apologize? Really, Mr. President?

I need to remind him of something he should already know. The nation was founded by a gang of dissenters who resisted Great Britain’s tax policies and its repression. The United States of America was created and the founding document guaranteed its citizens the right to criticize the government.

He keeps doubling, tripling and quadrupling down on this ridiculous feud with U.S. Reps. Alexandria Ocasio-Cortez, Alyanna Pressley, Rashida Tlaib and Ilhan Omar. He said they should return to “where they came from.” Hah! Three of them were born in the United States; the fourth is a Somali refugee who earned her citizenship.

They all know about the Constitution. They all are practicing their rights that the document guarantees them.

Now the head of state said they should apologize?

Get real. The president should apologize to the nation over his absolute and astonishing ignorance of what the Constitution allows and what it guarantees.
