Uncertainty looms over Julie Su's nomination for U.S. Labor Secretary.

President Biden's nomination of Julie Su as Labor secretary is in serious danger as Sen. Joe Manchin has told the Biden administration he has deep reservations about her. For Biden, Manchin’s opposition combined with one other Democratic defection would scuttle Su’s chances. It would mark the third defeat of a Biden nominee this year. With Senate Democrats facing a difficult map in 2024, vulnerable senators such as Manchin, Sinema, and Tester are looking for ways to create some political space from Biden.
