WASHINGTON (AP) — Legislation requested by President Barack Obama authorizing the military to arm and train moderate Syrian rebels fighting Islamic State militants in the Middle East is headed for his signature after a sweeping Senate vote. The bipartisan 78-22 tally Thursday blended support from Obama's close Democratic allies and some of his fiercest GOP critics, including top Senate Republican Mitch McConnell of Kentucky. The legislation also provides funding for the government after the end of the budget year on Sept.
