President Biden on Tuesday nominated Deputy Labor Secretary Julie Su to be his next secretary of Labor, potentially making her the first Asian American member of his Cabinet.

Su would replace Labor Sec. Marty Walsh, who left the administration to lead the National Hockey League Players’ Association. He was the first Cabinet secretary in the line of succession to leave his post since the start of the Biden administration.

Su, the former California labor secretary, was confirmed by the Senate to serve as deputy Labor secretary in a vote along party lines in July, 2021. Democrats currently control the Senate, 51-49, though Sen. John Fetterman (D-Pa.) is receiving treatment for depression at Walter Reed Medical Center.

The Biden administration is the first in more than 20 years not to have an Asian American Cabinet secretary and Biden was under pressure to name Su to the post since the news of Walsh’s resignation.
