Just hours before a scheduled press conference in which Attorney General Jeff Sessions is expected to announce the administration’s decision to end the Deferred Action for Childhood Arrivals (DACA) program in six months, President Trump indicated called on Congress to come up with a legislative solution.

In a short tweet, Trump said called on Congress to “get ready to do your job” when it comes to DACA.

Politico was first to report that the Trump administration was planning to announce Tuesday that he will end DACA, a move that has seen bipartisan pushback.

A few GOP members of Congress, like Sen. Lindsey Graham (R-SC), said they would be supportive of the President’s plan to end the program if it meant the anticipated six-month delay in ending the program was put in place to give Congress time to come up with a solution to help the “dreamers,” undocumented immigrants who came to the U.S. as minors.

The DACA program was introduced through executive order by former President Barack Obama in 2012 and is designed to protect undocumented immigrants who came to the U.S. as children from deportation.

The announcement coming Tuesday is in response to threats made by several states to sue Trump if he didn’t make moves to end the program by Tuesday.
