MANILA, Philippines (AP) — A Philippine senator and leading critic of President Rodrigo Duterte's deadly crackdown on illegal drugs petitioned the Supreme Court on Monday to nullify an arrest warrant for her on drug charges and release her from jail. De Lima said she was innocent of the charges of receiving bribes from detained drug lords while she headed the Department of Justice, adding that the accusations were part of an attempt by Duterte to muzzle critics of his anti-drug clampdown, which has left more than 7,000 suspected dealers and small-time users dead.
