U.S. officials said on Friday that almost 2,000 children were separated from adults at the border between mid-April and the end of May.

Simon Sandoval-Moshenberg, legal director of the immigrant advocacy program at the Legal Aid Justice Centre in Virginia, said he's never worked with immigrants who said US policies influenced their decision to move. The president has been anything but conciliatory on the matter.

Trump has said he wants the separations to end, but continues to blame opposition Democrats for the crisis, which critics say is one of his own making.
