On June 15, 2022, President Joe Biden nominated Plumb to be deputy undersecretary of defense for acquisition and sustainment. Hearings were held before the Senate Armed Services Committee on July 28, 2022. During that hearing, Senator Dan Sullivan placed a hold on Plumb's nomination over a dispute with the Biden administration over a mining project in his home state of Alaska. The committee favorably reported Plumb's nomination to the Senate floor on September 28, 2022. Plumb's nomination expired at the end of the year and was returned to President Biden on January 3, 2023. Plumb was renominated the same day. The committee favorably reported Plumb's nomination to the Senate floor on February 9, 2023. But later in February, Sen. Tommy Tuberville, R-Alabama, placed a hold on all Defense Department nominations and general officer promotions because he disagrees with new department policies that help troops travel for reproductive care if they serve in states that heavily restrict abortion. On April 17, 2023, the United States Senate invoked cloture on her nomination by a 61–26 vote. On April 18, 2023, her nomination was confirmed by a 68–30 vote. Personal life
Plumb is married to John F. Plumb, who as of 2023 serves in another post within the United States Department of Defense. References
