As the Trump administration announced its decision to “wind down” former President Barack Obama’s Deferred Action for Childhood Arrivals (DACA) program, it pushed Congress to take on the issue through legislation.

The program, enacted in 2012, has provided about 800,000 young immigrants the ability to work legally in the country while also having temporary relief from deportation.

In his announcement this morning, Attorney General Jeff Sessions said the program’s “open-ended circumvention of immigration laws was an unconstitutional exercise of authority by the Executive Branch.”

Sessions added that it was up to Congress to come up with protections for the program’s “dreamers,” a statement that the president echoed in his reaction to this morning’s announcement.

White House spokeswoman Sarah Huckabee Sanders said in a briefing Tuesday that President Donald Trump wants to see “responsible immigration reform” from Congress. She says it should also include controlling the U.S. border, improved vetting and enforcing immigration laws.

Trump said in his statement that he was “not going to just cut DACA off, but rather provide a window of opportunity for Congress to finally act.”
