Defying a chorus of corporate executives and critics in Congress, President Donald Trump is expected to announce on Tuesday that he will roll back protections that spare children brought to the United States illegally from being deported.

But Trump reportedly will only begin enforcing the change in policy after a 6-month delay. It’s unclear how that might work, but it could give Congress some time to decide whether to turn the Obama-era program — called Deferred Action for Childhood Arrivals, or DACA — into law.
