In a series of tweets over the weekend and Monday morning, President Donald Trump made claims about immigration policy; border security; the Deferred Action for Childhood Arrivals, or DACA, program; and the debate in Congress. Roll Call fact-checked some of Trump’s assertions, many of which are not true.

Claim: DACA is “dead.”

Trump first announced his intention to end DACA last September, and ordered the Homeland Security Department to begin winding the program down in early March. But two federal judges have blocked his efforts, leaving the program largely intact and keeping about 700,000 young undocumented immigrants known as “Dreamers” in limbo.

DHS isn’t accepting new applications, but it is renewing existing benefits for Dreamers brought to the U.S. illegally as children. That’s likely to remain the case until the legal challenges are resolved or Congress legislates a permanent solution for DACA beneficiaries. Ongoing appeals are expected to take months, and the case could end up before the Supreme Court.

Claim: DACA is “dead” because Democrats “didn’t care or act.”

Members of both parties have offered proposals to solve the current crisis. Democrats have tended to make a solution for Dreamers the centerpiece of proposals in exchange for border security improvements. Trump and congressional Republicans, meanwhile, have demanded steep concessions in return for helping Dreamers, including cuts to legal immigration, punishment for so-called sanctuary cities and billions of dollars for the U.S.-Mexico border wall.

Democrats and Republicans worked together in February to reach a workable compromise that could garner the 60 votes necessary to pass the Senate. One proposal to grant citizenship for Dreamers in exchange for border security and other immigration priorities brokered by Sens. Mike Rounds, a South Dakota Republican, and Angus King, a Maine independent, got 54 votes. Trump’s proposal, on the other hand, only received 39. Fourteen Republicans voted against the Trump proposal.
