U.S. Rep. Luis Gutierrez needs to chill out. He needs to take a breath. He needs to rethink the insult he hurled at one of Donald Trump’s more celebrated and worthy appointees.

The Illinois Democrat is angry that the president decided to rescind the Deferred Action for Childhood Arrivals order signed by President Barack Obama. He’s so angry that he said that White House chief of staff John Kelly has “disgraced the uniform he used to wear” by enabling the president to rescind this order.

I have two words for Rep. Gutierrez: Shut. Up.

I will stipulate first of all that I agree that the DACA rescission is a mistake. I wish the president had not done it. I believe DACA rules are humane, in that they protect undocumented immigrants who were brought to this country as children illegally by their parents; many of them know no other country than the United States of America. They deserve a clear and unfettered path to citizenship or permanent legal immigrant status.

But to say that Kelly — a retired Marine Corps general and a Gold Star father whose son was killed in combat in Afghanistan — goes far beyond what is decent and honorable.

I get that Gutierrez is emotional about immigration reform. He feels it in his gut. But let’s put the hyper-heated and defamatory rhetoric in cold storage while we discuss DACA, shall we?

Oh, one more thing: Luis Gutierrez’s own military service? None.
