President Trump urged Democrats to “make a deal” on the Deferred Action for Childhood Arrivals program Monday, but said any proposal that lacks border security measures and funding for his border wall is “a total waste of time.”

“Any deal on DACA that does not include STRONG border security and the desperately needed WALL is a total waste of time. March 5th is rapidly approaching and the Dems seem not to care about DACA. Make a deal!” Trump tweeted Monday.

The president announced in September he would be rescinding the DACA program effective March 5, giving Congress six months to pass legislation.

Since then, Democrats and Republicans have been working to draft a deal addressing Dreamers, the name given to those who were brought to the U.S. illegally as children and were protected from the threat of deportation under DACA. Trump has said any such measure must include funding for his border wall and other border security measures.

The White House released the president’s framework for an immigration deal last month. The proposal included $25 billion for the border wall and other border security measures, and would provide a pathway to citizenship for 1.8 million young immigrants. Trump’s plan also ended the visa lottery program and limited chain migration.

But many Democrats are opposed to the wall.
