Trump is positioning himself with conservatives in the Republican Party who say the bipartisan compromise falls well short of what is needed to fix the nation’s immigration system.

But the comments could lengthen the impasse in Congress, where lawmakers are scrambling to pass a fix for the Obama-era Deferred Action for Childhood Arrivals (DACA) program, which Trump scrapped last year.

Democrats are demanding that Congress pass protections for recipients of the program, who are allowed to live and work in the U.S. without fear of deportations.

But Trump expressed confidence both sides could work out a deal.

“Time is running out,” he said.

The DACA program will begin winding down on March 5 .

The immigration talks reached an abrupt impasse late last week, after Trump made vulgar comments about Haiti, El Salvador and African nations in an Oval Office meeting with a bipartisan group of lawmakers, some of whom had crafted a specific plan.

Trump has denied that he called the nations “shithole countries,” but said the U.S. must not accept high levels of immigration from countries with high crime and poverty rates.

The bipartisan plan would offer many young immigrants a pathway to citizenship in exchange for billions of dollars in border-security measures and tweaks to the visa system.

on Wednesday The White House announced it supports the short-term bill.
