The White House on Friday refused to say whether Vice President Mike Pence is planning to be in the Senate early next week in case he’s needed to help get Betsy DeVos confirmed as President Trump’s secretary of education.

Republican Sens. Susan Collins and Lisa Murkowski announced earlier this week that they will not vote for DeVos on the Senate floor, and unless a Democrat decides to support her, Pence would be needed to break a possible 50-50 tie and get her confirmed.
