WASHINGTON >> President Donald Trump is expected to announce that he will end protections for young immigrants who were brought into the country illegally as children, but with a six-month delay, people familiar with the plans said today.

The delay in the formal dismantling of the Deferred Action for Childhood Arrivals, or DACA, program would be intended to give Congress time to decide whether it wants to address the status of the so-called Dreamers in legislation, according to two people familiar with the president’s thinking. But it was not immediately clear how the six-month delay would work in practice and what would happen to people who currently have work permits under the program, or whose permits expire during the six-month stretch.

It also was unclear exactly what would happen if Congress failed to pass a measure by the considered deadline. Two people familiar with the president’s thinking spoke on condition of anonymity because they were not authorized to discuss the matter ahead of a planned Tuesday announcement.

The president, who has been grappling with the issue for months, has been known to change his mind in the past and could still shift course.

Trump has been wrestling for months with what to do with the Obama-era DACA program, which has given nearly 800,000 young immigrants a reprieve from deportation and the ability to work legally in the form of two-year, renewable work permits.

The expected move would come as the White House faces a Tuesday deadline set by Republican state officials threatening to continue sue the Trump administration if the president did not end the program. It also would come as Trump digs in on appeals to his base as he finds himself increasingly under fire, with his poll numbers hanging at near-record lows.
