Top US Democrat Pelosi says to step down from party leadership

Democrat Nancy Pelosi, the trailblazing first female speaker of the US House of Representatives, says that she will step down from the party leadership when Republicans take control of the chamber in January. "For me, the hour has come for a new generation to lead the Democratic caucus that I so deeply respect," says the 82-year-old Pelosi, who first became speaker in 2007 and later presided over both impeachments of Donald Trump.
