President-elect Joe Biden will reportedly nominate a White House budget director who has been one of the country’s most prominent critics of US Sen. Bernie Sanders and who has previously backed Social Security cuts.

Biden — who has repeatedly pushed for Social Security cuts throughout his career — announced his selection of Center for American Progress (CAP) president Neera Tanden as his choice to run the powerful White House Office of Management and Budget (OMB). A longtime aide to Hillary Clinton, Tanden touted her think tank’s 2010 proposal to reduce Social Security benefits in 2012, as Biden was pushing for such cuts in the Obama administration.

Tanden’s Social Security push followed the 2010 midterms, during the deficit reduction negotiations between the Obama administration and the new GOP Congress. Republicans drew a hard line, but Obama sought a middle ground. Central to the administration’s efforts, which were led by Biden, was a plan called the “chained CPI” that would have slowed the rate at which Social Security benefits increase over time.
