Senate Democrats unsuccessfully attempted to delay a vote until after the release of a batch of emails ordered by an Oklahoma judge. On February 17, 2017, the Senate confirmed Pruitt, by a vote of 52–46, to be the Administrator of the Environmental Protection Agency. The vote was mostly along party lines, with Republican Susan Collins voting against, and Democrats Joe Manchin and Heidi Heitkamp voting in favor (Republican John McCain and Democrat Joe Donnelly did not vote). Pruitt was sworn in the same day by Supreme Court Justice Samuel Alito.
