CNN reports that Homeland Security Secretary Kelly is not sanguine on DACA. Kelly was said to have discussed DACA with Attorney General Jeff Sessions, who was noncommittal on defending it in court. Presumably because the related DAPA program has been officially wound down, there are pending court cases to which states might add complaints about DACA, the article states.
The article also mentioned bipartisan legislation such as the BRIDGE Act, announced in December 2016 but currently in limbo, about which Secretary Kelly was apparently unaware.
