Re “Trump Moves to End DACA and Calls on Congress to Act” (nytimes.com, Sept. 5):

The abolition of Deferred Action for Childhood Arrivals, or DACA, would be the cruelest measure of many cruel measures adopted by President Trump since he took office. A six-month delay is a joke, and a way for Mr. Trump to ease the incredible pain he will cause.

Immigrants have made America great, and the children of immigrants, legal or illegal, have contributed mightily to our greatness. To abandon more than three-quarters of a million Dreamers simply because their parents entered this country illegally would not only be a travesty, but also a sapping of one of our greatest potential resources.

Mr. Trump is obsessed with Barack Obama, and instead of governing, he has set out to destroy everything Mr. Obama put in place. Leave the children be, Mr. Trump. You have already caused more harm to our nation than anyone thought possible.

My family and I had the opportunity to host several Dreamers for the weekend so they could visit New York City for the first time. Rather than immediately going off to see the sights, as I suspect my own college-age children would have done, they pulled out their laptops and studied for an exam the entire evening before touring New York the next day.
