(AP) — Republicans have won control of the U.S. House, returning the party to power in Washington and giving conservatives leverage to blunt President Joe Biden’s agenda and spur a flurry of investigations. But a threadbare majority will pose immediate challenges for GOP leaders and complicate the party’s ability to govern. More than a week after Election Day, Republicans secured the 218th seat needed to flip the House. The full scope of the party’s majority may not be clear for several more days — or weeks — as votes in competitive races are still being counted.
