The revocation came on the fifth anniversary of another effort that has protected hundreds of thousands of young immigrants from deportation. Yet as president, he repeatedly expressed empathy with the young participants in the program known as Deferred Action for Childhood Arrivals program, or DACA. As a candidate, Donald Trump denounced the program as an "illegal amnesty" and said he would immediately end it. But his administration has continued to receive applications and renewal requests and grant work visas to eligible individuals since he took office in January. Cancelling the program could mean trying to deport more than 787,000 people who identified themselves to the government in exchange for temporary protection.
While dreamers scored a win with the president latest decision, DAPA, a program to extende the same protection to parents have been eliminated by the adminsitration. Courts had blocked it pending further litigation, which has been ongoing. "In the case of DAPA. that was immediately enjoined by the courts and it languished in limbo for now I think two or three years, so my action was just to do a little house cleaning and I canceled the memo".
But one line of the memorandum noted that Obama's 2012 order that shielded Dreamers - young people who came to the US illegally as children - "will remain in effect".
Kelly did not respond to a question about what reassurances DACA recipients have that their status won't be changed on a moment's notice.
Homeland Security Department spokesman David Lapan says no decisions about DACA's ultimate fate have been made. Such legislation has not materialized.
The program protects the immigrants, known as "Dreamers", from being deported, and helps them obtain work permits so they can be legally employed.
Fresh Ideas: Whose interests is Trump protecting in ditching Paris climate accord?
That accord is known as the Paris Agreement and it consists of voluntary national contributions to limit climate change. Former President Barack Obama pledged the U.S.to reducing annual greenhouse emissions by 1.6 billion tons by 2025.
The program to protect parents was announced by President Barack Obama in November 2014 but was never fully launched. Arrests of immigrants inside the USA have increased under the Trump administration, but deportations are slightly down as fewer people have been caught crossing the Mexican border into the United States illegally. "The preservation of DACA is a tribute to the strength of the Dreamer movement and an acknowledgment - at least in part - by the Department of Homeland Security that it should not be targeting undocumented immigrants who have strong ties to their communities and have abided by the law".
But a White House official separately insisted that "there has been no final determination on DACA", leaving it, and the fate of the estimated 750,000 who have won work permits under the program, uncertain.
Sen. Tom Carper, D-Del., said keeping DACA in place was "common decency" and expressed relief that the dreamers "now have the certainty they deserve". "He still has four years to go", she said.
While Trump will not terminate the DACA program, Secretary of Homeland Security John F. Kelly announced he had rescinded a memo created during Obama's presidency, which protected parents of US citizens from deportation. His move to do so was largely symbolic. Homeland Security John Kelly formally revoked a policy memo that created the Deferred Action for Parents of Americans programme.
Still, it gave Trump a chance to claim he was following through on one campaign pledge, even as he wasn't delivering on another.
