Martin O’Malley resigned as Social Security Administration Commissioner effective at the end of November. President Biden tapped Carolyn Colvin, who previously served as Acting Commissioner of Social Security from 2013 to 2017, to serve in that capacity during the transition into the Trump Administration.

O’Malley served as Commissioner of SSA since December 20, 2023, and is seeking to become chairman of the Democratic National Committee.

Colvin originally joined Social Security in 1994 and has served in many roles there in the past 30 years. She returned as senior advisor to O’Malley in January of this year after initially retiring in 2017.

Colvin’s return as Acting Director will be short-lived. Earlier this week, President-elect Trump selected Frank Bisignano, the Chief Executive Officer of Fiserv, as his nominee to be the next Commissioner. Bisignano will need to be confirmed by the U.S. Senate.
