Donald Trump has no sense of decency. None. Nothing, man!

He now is threatening to send illegal immigrants to those so-called “sanctuary cities” as a cudgel to batter congressional Democrats he says refuse to enact any meaningful improvements to the nation’s immigration laws.

Wow! How do you fathom that a president of the United States would actually do such a thing? If you can, then you’re far better than I am.

Sanctuary cities, you’ll recall, are those communities that establish themselves as “sanctuaries” for illegal immigrants. Texas legislators two years ago passed a law banning such cities in this state. Truth be told, I am not a fan of sanctuary cities, either. The policy does little if anything to advance the cause of immigration reform, which, by the way, is what many congressional Democrats are seeking instead of the ham-handed approach that the Trump administration is taking to combat the issue of illegal immigration.

Indeed, this threat to send undocumented immigrants to sanctuary cities is a profound demonstration of the heartlessness that Trump exhibits every single day as president of the United States of America.

California Attorney General Xavier Becerra — a former member of Congress — calls the president’s threat a sign of “vindictiveness” reminiscent of the Watergate era.

I agree with him. Good grief, Mr. President, sit down with your foes and start working seriously and diligently on a comprehensive plan to reform our nation’s immigration system.
