WASHINGTON (AP) — Prospects for action on the nation’s border crisis faded Thursday as lawmakers traded accusations rather than solutions, raising chances that Congress will head out for its summer recess without doing anything about the tens of thousands of migrant children streaming into South Texas.

Republican Sen. Ted Cruz of Texas announced plans to try to cancel out President Barack Obama’s two-year-old policy that granted work permits to hundreds of thousands of immigrants brought illegally to the country as youths, saying it was causing the crisis — something the administration disputed. “The problem will not be solved until we make clear that those coming here illegally will not be granted amnesty,” Cruz declared.
