At a Tuesday afternoon meeting with nearly a dozen senators deeply involved in immigration policy, White House chief of staff John Kelly pledged that the administration will soon present a list of border security and other policy changes it wants as part of a broader deal on so-called Dreamers, according to people who attended the meeting. The plan could come in a matter of days, senators said.

About a half-dozen senators have been negotiating a bipartisan package prompted by Trump’s decision to kill the Deferred Action for Childhood Arrivals program, an Obama-era executive action that granted work permits to nearly 800,000 undocumented immigrants who came here as minors. Yet the senators could not fully flesh out a deal before they knew what Trump was willing to sign.

“We couldn’t finish this product, this bill, until we knew where the administration was,” Sen. Jeff Flake (R-Ariz.), who has been negotiating a DACA compromise for weeks, said in an interview after the meeting with Kelly. “And that’s why this meeting was so important.”
