Obama tweeted his reaction, which described Trump’s decision as wrong and “contrary to our spirit, and to common sense.”

To target hopeful young strivers who grew up here is wrong, because they’ve done nothing wrong. My statement: https://t.co/TCxZdld7L4 — Barack Obama (@BarackObama) September 5, 2017

With one swift response, “Captain America” actor Evans summed up why the former president’s statement meant so much to so many.

Trump’s decision puts into uncertainty the futures of roughly 800,000 young undocumented immigrants who came to the U.S. as children, also known as Dreamers.

The president also put the responsibility on Congress to craft a legislative replacement for DACA before the Obama-era rule is eliminated in six months. Republicans and Democrats have disagreed on protections for Dreamers in the past.
