President Joe Biden is set to announce that his administration is expanding eligibility for Medicaid and the Affordable Care Act's health insurance exchanges to hundreds of thousands of immigrants brought to the U.S. illegally as children, according to two U.S. officials briefed on the matter. The action will allow participants in the Obama-era Deferred Action for Childhood Arrivals program, or DACA, to access government-funded health insurance programs. The 2012 DACA initiative was meant to shield from deportation immigrants brought to the U.S. illegally by their parents as young children and to allow them to work legally in the country.
