What everyone in the White House agrees: It's up to Congress to act if members want to preserve the principles of DACA and protect these illegal immigrants who came to America as children.

Trump's advisers know that Congress only acts when there's a crisis. Tuesday's announcement is expected to force such action.

Trump is expected to rescind DACA but will likely give Congress a window to act before the effects of the termination are felt.
But, there's no chance Congress will pass a bill that gives permanent legal status to any class of individuals without attaching serious enforcement measures to the same bill.
