UPDATED 2:19 p.m. | President Donald Trump is expected to announce Saturday afternoon that he would sign legislation to extend protections to Deferred Action for Childhood Arrivals recipients and individuals with Temporary Protected Status in exchange for the $5.7 billion for border security money that he has wanted for a southern border wall, a source involved in planning the announcement confirmed.

As always, however, nothing is official until the president himself actually makes the public commitment. Trump is now scheduled to make his border security-shutdown announcement at 4 p.m., Eastern time, Saturday.

The legislation would contain a version of the so-called Bridge Act, which protects undocumented immigrants brought to the U.S. as children, also known as “Dreamers.” The stalemate over funding for the border wall has resulted in a partial government shutdown that’s now in its 29th day.

Democrats on Capitol Hill panned the Trump proposal, with a senior House Democratic aide saying that it could not pass in either chamber.

“Democrats were not consulted on this proposal. Similar inadequate offers from the Administration were already rejected by Democrats. The BRIDGE Act does not fully protect Dreamers and is not a permanent solution,” the aide said in a statement. “This is not a compromise as it includes the same wasteful, ineffective $5.7 billion wall demand that shut down the government in the first place.”
