President Donald Trump on Friday said he wanted two major concessions in exchange for legal protections for hundreds of thousands of young immigrants who came to the United States as children.

The president's demands potentially complicate bipartisan talks about shielding those immigrants from deportation. Congress faces a March 5 deadline to pass legislation after Trump ended the Obama-era Deferred Action for Childhood Arrivals program in September, with a six-month delay.

In a tweet, Trump claimed that Democrats "have been told, and fully understand, that there can be no DACA without the desperately needed WALL at the Southern Border and an END to the horrible Chain Migration & ridiculous Lottery System of Immigration etc."

"We must protect our Country at all cost!" he wrote.

Democrats have previously signaled that they could agree to Republican demands for more border security funding in exchange for a fix to DACA. However, they have resisted Trump's calls to fund a physical barrier on the Mexican border.
