In a breakthrough that could shield 800,000 undocumented immigrants from deportation, top congressional Democrats said Wednesday they’ve reached a deal with President Trump to protect immigrants who were brought to the U.S. as children. The deal came after Senate Minority Leader Chuck Schumer and House Minority Leader Nancy Pelosi met with President Trump over a dinner of Chinese food at the White House. In a joint statement, the Democratic leaders said Trump agreed to support legislation that would enshrine the protections of DACA into law. DACA is the Deferred Action for Childhood Arrivals program, which gives legal protection to young undocumented immigrants to live and work in the United States. But early Thursday, President Trump cast doubt over any agreement, tweeting, “No deal was made last night on DACA. Massive border security would have to be agreed to in exchange for consent. Would be subject to vote.” The reported agreement enraged many Republicans, including Iowa anti-immigrant Congressmember Steve King, who retweeted an Associated Press report on the deal, adding, “If AP is correct, Trump base is blown up, destroyed, irreparable, and disillusioned beyond repair. No promise is credible.”
