Biden Ousts Trump Holdovers from Social Security Administration Removal of the agency’s leadership follows a Supreme Court decision finding that laws barring a president from firing political appointees without cause are unconstitutional. The Biden administration on Friday fired Social Security Commissioner Andrew Saul and Deputy Commissioner David Black, following months of lobbying by advocacy groups and federal employee unions. Kilolo Kijakazi, the agency’s deputy commissioner for the retirement and disability policy and a Biden appointee, will lead the agency on an acting basis. Kijakazi announced the ouster of Saul and Black, both holdovers from the Trump administration, in an email to Social Security employees Friday afternoon.
