WASHINGTON (AP) — The Bush administration quietly withdrew in the weeks after Barack Obama’s election a new rule requiring high-level approval before federal agents nationwide could arrest fugitive immigrants. The future for Obama’s aunt, who had been living in the country illegally, will be determined at an immigration court hearing in April. The Homeland Security Department had originally imposed the unusual directive days before Obama’s election, an order that would have affected Zeituni Onyango, the half-sister of Obama’s late father.
