On Capitol Hill, the Senate is set to begin a debate on immigration today. Lawmakers are expected to debate how to handle the future of DACA—that’s the Obama-era program Deferred Action for Childhood Arrivals, which gave 800,000 young undocumented people permission to live and work in the United States before President Trump canceled the program last year. President Trump has proposed opening a path to citizenship for about 1.8 million undocumented people in exchange for a slew of dramatic anti-immigrant measures, including $25 billion in funding for a border wall, as well as ending the family reunification program and the diversity lottery, which primarily benefits immigrants from Africa.
