Nancy Pelosi: I asked President Trump to reassure DREAMers they would be safe for now

President Trump on Thursday assured DREAMers that they didn't have to worry over the next six months as Congress works on saving the immigration program that has shielded them from deportation.

And he sent that tweet after House Minority Leader Nancy Pelosi told the president that the 800,000 young people protected under the program needed the assurance, following the administration's announcement that it was winding down the Deferred Action for Childhood Arrivals program, or DACA.

Trump gave a six-month deadline for Congress to pass legislation that would preserve the program that covers undocumented people who were brought into the country as children.

Many people – from so-called DREAMers whose fates are now uncertain, to members of the faith-based and business communities – are concerned what the next six months will bring.

"That's why I said to him, when he called this morning, 'People really need assurance from you, Mr. President, (that) the six-month period won't be a roundup,'" Pelosi, D-Calif., told reporters.

Prior to Pelosi's presser, the White House confirmed that Trump spoke with Pelosi, as well as Senate Majority Leader Mitch McConnell, R-Ky., and Senate Minority Leader Chuck Schumer, D-N.Y. He will also have dinner with Speaker Paul Ryan.

Trump spokeswoman Sarah Huckabee Sanders did not confirm the reports about Pelosi's tweet request.

"The president is committed to working across the aisle and doing what is needed to best serve the American people," Sanders said, according to pool reports.

Pelosi also said that the president had indicated he would sign legislation that would preserve DACA.

"The president, both yesterday and today, made it very clear that he wants Congress to act to get this done," she said.

She noted that the time to pass a bill is now, while public interest is high and largely in support of DREAMers.

While the president said he would "revisit" the issue if Congress is unable to pass a bill, Pelosi argued that he wouldn't be able to – given that Attorney General Jeff Sessions made the legal argument that DACA was an "unconstitutional exercise of authority by the executive branch." The Obama administration created DACA after Congress failed to push through legislation.

"Congress should act and remove all doubt," Pelosi said. "There should be statutory protection for DREAMers."

Still, these agreements between Trump and congressional leaders didn't necessarily signal that a new dawn of cooperation between the branches is coming, Pelosi said.

"Let's hope this is a sign of interest to come, but you never know where your shared interest might be," she said.
