The Senate is set for a showdown at noon Tuesday that will likely see Betsy DeVos, President Trump's nominee for education secretary, confirmed by the slimmest of margins with the help of Vice President Mike Pence, who is expected to cast a tie-breaking vote. DeVos, who has been uniformly opposed by Senate Democrats, is perhaps the most reviled pick among Trump's Cabinet and administration selections. A staunch supporter of school choice, DeVos faced contentious confirmation hearings and even saw two Republicans break ranks and oppose her nomination.
