It’s hard to believe, but Donald J. Trump once stood tall for the cause of “due process.”

A one-time White House staff secretary, Rob Porter, faced accusations that he beat up two former wives. He was forced to quit amid storms of protest.

The president then asked out loud about whatever happened to “due process.” Why, Porter deserved the same level of due process that the country grants to everyone else, Trump said.

That was then.

These days, due process has been kicked to the curb. The president now believes that every immigrant who comes into the country illegally should be rounded up and kicked out immediately. Due process be damned! They don’t need any adjudication, he said.

What gives? Does the president favor due process or not?

Sure, I get that he’s trying to make a political point. However, some principles should withstand political pressure.

U.S. law allows illegal immigrants to have their cases heard by the judicial system. Judges have an obligation, according to the law, to hear the immigrants’ stories and decide — based on the law — how their case should be resolved.

The president, though, says that’s no longer necessary.

Get ’em out of here, he says. All of ’em! Refugees? Those fleeing persecution? Violence? Forget about it!

Kick them all out, he says. Now!

Shameful.
