By international law, the so-called refugees were required to request asylum in the first country that offered such. Mexico them offered asylum, and the “refugees” refused that offer. Therefore, the United Sates has the full legal right to deny these fools entry and asylum. Moreover, the president has full constitutional authority to decide who is to be admitted into this country - and that dispute was already settled by the SCOTUS.
