The Senate's about-face Wednesday night stemmed from a procedural hold Sen.
Kevin Cramer (D-N.D.) placed on the nomination — a parliamentary tactic that allows a senator to slow down a nominee — over an issue unrelated to Wormuth. Cramer said the Senate mistakenly approved her nomination before he had removed the hold, requiring leadership to backtrack.
"I had a hold on her. I think you probably all suspected that," Cramer told reporters Thursday. "They accidentally confirmed her by [unanimous consent] and then they unconfirmed her ... because I hadn't lifted my hold. But I did today. So that's what happened last night."
