In other Senate news, the confirmation of Betsy DeVos as education secretary appears to be on thin ice as two Republicans—Senators Susan Collins and Lisa Murkowski—announced plans to vote against DeVos, leaving Senate Republicans one vote short of confirming her. If the Senate vote is 50-50, Vice President Mike Pence would then cast the deciding vote—an event that has never happened to any other presidential nominee in history. DeVos is a longtime backer of charter schools and vouchers for private and religious schools. She and her husband have also invested in a student debt collection agency that does business with the Education Department.
