In United States, Senate has confirmed President Donald Trump's controversial nominee for Education Secretary, Betsy DeVos, by the slenderest possible margin. US Vice-President Mike Pence cast the tie-breaking vote to secure her cabinet role, splitting the chamber 50-50. <br/><br/>It was the first time ever that a Vice- President has interceded in such a way for a Cabinet Secretary. Mrs DeVos, a billionaire, who has no experience with public schools, faced a rocky confirmation hearing last month. Senate Democrats staged a 24-hour debate into yesterday to hold up her confirmation.
