Andrew Marshall Saul (born November 6, 1946) is an American businessman and political candidate who served as the 16th commissioner of the United States Social Security Administration from 2019 to 2021.

Saul previously served as the chair of the Federal Retirement Thrift Investment Board (FRTIB) and vice chairman of the New York Metropolitan Transportation Authority.

[5] Saul began his career with Brooks Fashion Stores, rising to become its president, and growing the company into a large corporation listed on the New York Stock Exchange.

[17] In 2006, Saul was appointed by Governor George Pataki to a six-year term as a vice-chairman of the Metropolitan Transportation Authority after nine years as a board member.

[19] Saul was nominated by President George W. Bush and confirmed by the United States Senate in 2002 as chairman of the Federal Retirement Thrift Investment Board, the agency which manages the Thrift Savings Plan for employees of Federal Government agencies, and soldiers in the Armed Services, providing retirement security for more than 3.7 million participants.

[20][21] Saul replaced James H. Atkins of Arkansas, who had been nominated to a third term by President Bill Clinton in a recess appointment.

"[24] During his confirmation hearing, Senator Daniel Akaka told Saul he would be facing a difficult situation, as the outgoing executive director had taken a number of actions before his sudden departure which led to "demoralization of the TSP staff, expensive lawsuits, investigations, rancorous battles with other agencies, along with the costs of a failed record keeping system project" that were all eventually dealt with by the FRTIB.

[26] It has been alleged by former FRTIB Chairman and Executive Director Roger Mehle that this occurred when Petrick wished to pursue a lawsuit against the contractor for the record keeping system which led to a conflict with the Justice Department over whether the board had standing to sue.

[29][30] Saul, and his executive director Gary Amelio, inherited a mishandled computer project for a new record-keeping system, which had been started in 1997 and wasted $36 million.

[32] Following the resignation of Gary Amelio in 2007, Saul appointed Gregory T. Long as executive director for the Thrift Savings Plan.

[33] In June 2007, the Federal Thrift Retirement Investment Board approved a resolution to prohibit Congress from proposing that companies that do business in Iran or Sudan be removed from the Thrift Savings Plan, in order to reduce support for Iran's oil and gas industry or to reprimand the Sudanese government for its role in the Darfur conflict.

[40] The Board also felt that participants are asked to absorb the cost of a loan program that they rarely use, and that the borrowers were also tying up the TSP's limited staff resources, leading to the changes.

[43] Along with Bill Kristol and Peggy Noonan, Saul is a trustee of the Manhattan Institute for Policy Research, a prominent conservative think-tank which promotes limited government and free-market principles whose mission is to "develop and disseminate new ideas that foster greater economic choice and individual responsibility" and has hosted policy speeches by then-National Security Advisor Condoleezza Rice in 2002 and both President Bush and Vice President Dick Cheney in 2006.

[51] Another Republican candidate, Iraq War veteran Kieran Lalor, criticized Saul as being too liberal, saying he was "Sue Kelly all over again".

The first FEVS report issued under Saul shows SSA dropped two ranks in the annual Best Places to Work in the Federal Government list.

[59] Saul said his discharge was illegal, despite two recent Supreme Court precedents saying that the president does have the authority to fire the head of an independent agency.

[60] Saul also responded by comparing his termination to the attorneys fired in Nixon's "Saturday Night Massacre", and that he would continue to do his job remotely, pointing out that his six-year term would not expire until 2025.
