It’s becoming a throw-away line, an automatic “out” for every ridiculous statement that flies out of Donald John Trump Sr.’s mouth.

The president received a direct question the other day. A reporter asked the vacationing president what he thought of Russian President Vladimir Putin’s decision to expel 755 U.S. diplomats. Trump’s response was to “thank” Putin for reducing the U.S. diplomatic service’s payroll.

So, with that idiotic response, the president of the United States effectively told those diplomats — and their Russian allies in the U.S. mission — that they don’t matter. He didn’t thank them publicly for their service. He didn’t say a negative word about Putin’s response to our government’s decision to impose sanctions on the Russian government over its meddling in the 2016 presidential election.

Oh, no. He didn’t go there.

Did he mean what he said? White House flacks said he was being “sarcastic.” Really?

Well, where is the disclaimer from the president? Why didn’t he reveal his sarcasm in the moment? Why did he in effect send the message to our Russia mission staff that they don’t matter, that their work and their years of service to the nation is of no value?

I do not believe there was a hint of sarcasm in what Donald Trump said. I believe instead that he engaged his mouth without first thinking of the consequences that his words carry.

This is yet another disgraceful demonstration of a president who “tells it like it is.”
