President Joe Biden and first lady Jill Biden are holding an event marking the 12th anniversary of the passing of the Deferred Action for Childhood Arrivals program at 2:45 p.m. Tuesday.

He is expected to use the occasion to announce sweeping immigration reform to speed a pathway to legal residency for about 500,000 illegal immigrants living in the United States. The actions will focus on spouses of U.S. citizens.
