*The GAO ruled on March 6, 2018 that Berryhill was unauthorized to serve as acting commissioner from November 17, 2017; however, she functionally continued to lead the agency.
Nancy Ann Berryhill is the former acting Commissioner of the Social Security Administration.[1] On March 6, 2018, the Government Accountability Office stated that as of November 17, 2017, Berryhill's status violated the Federal Vacancies Reform Act, which limits the time a position can be filled by an acting official; "[t]herefore Ms. Berryhill was not authorized to continue serving using the title of Acting Commissioner after November 16."[2][3] Berryhill responded that "Moving forward, I will continue to lead the agency from my position of record, Deputy Commissioner of Operations."[4]
On April 17, 2018, President Trump nominated Andrew Saul to the position of Commissioner of Social Security. This action allowed Berryhill to regain the title of “Acting Commissioner;"[5] she held that position until Saul was confirmed by the United States Senate on June 4, 2019.
