The US Senate was poised to vote Tuesday on President Donald Trump's choice for education secretary -- Betsy DeVos, a deeply controversial billionaire champion of taxpayer-funded alternatives to public education. After debating through the night, the Senate scheduled a vote for noon (1700 GMT), with Vice President Mike Pence likely to step in to break a tie, in a rare intervention allowed under the US Constitution. / AFP / JIM WATSON (Photo credit should read JIM WATSON/AFP via Getty Images)
