WASHINGTON (Reuters) - The U.S. House of Representatives on Thursday took a step toward averting a partial government shutdown at the end of this week, approving rules to debate a bill that would fund federal agencies through Jan. 19. Also cleared for debate was an $81 billion disaster aid bill to help U.S. states, Puerto Rico and the U.S. Virgin Islands recover from a series of recent natural disasters. House votes on both bills were expected later on Thursday.
