THURMONT, Md. (AP) — The Latest on President Donald Trump's meetings at Camp David with congressional leaders (all times local): 1:50 p.m. President Donald Trump says he won't sign legislation protecting hundreds of thousands of young people brought to the country illegally as children unless Congress agrees to overhaul the legal immigration system. Trump told reporters Saturday at Camp David that any deal must include an overhaul of the family-based immigration system as well as an end to the diversity visa lottery, which draws immigrants from under-represented parts of a world. That's in addition to funding for his promised southern border wall and added border security.
