President Donald Trump said that there will be no deal to legalize the status of young adult immigrants called Dreamers and he said the U.S.-Mexico border is becoming more dangerous.

After tweeting a “Happy Easter” message on Twitter, he said: “Border Patrol Agents are not allowed to properly do their job at the Border because of ridiculous liberal (Democrat) laws like Catch & Release. Getting more dangerous.

“‘Caravans’ coming. Republicans must go to Nuclear Option to pass tough laws NOW. NO MORE DACA DEAL!” he wrote, adding a threat to kill the North American Free Trade Agreement which is being renegotiated with Mexico and Canada.

Trump had said he was open to a deal with congressional Democrats who want to protect DACA in exchange for funding to build a U.S.-Mexico border wall, a campaign trail promise.

DACA, or Deferred Action for Childhood Arrivals, is a program created in 2012 under Democratic former President Barack Obama that Trump sought to rescind last autumn.

Designed for people brought to the United States as children by parents who were undocumented immigrants, the program shielded them from deportation and gave them work permits.
