At his Senate confirmation hearing Tuesday, Rep. Mick Mulvaney (R-S.C.), President Trump's nominee for director of the Office of Management and Budget, clarified that he does not think Social Security or Medicare are "unconstitutional" — despite his vote in the South Carolina Senate in 2009 declaring both programs exactly that. He also reassured the Senate Budget Committee that his description of Social Security as a "Ponzi scheme" was simply a way of explaining the program's cash flow. "I wouldn't read too much into [my] description of it as a Ponzi scheme," Mulvaney said.
However, while Mulvaney said he would not "be arguing to the president of the United States" that either of those programs are "unconstitutional," he did indicate he would push Trump to make changes to entitlement programs, which Trump has promised not to cut. "The only thing I know to do is tell the president the truth," Mulvaney said, arguing that the programs are not sustainable and that funds would soon run dry; he suggested means-testing Medicare or raising the retirement age for Social Security.
Even before Mulvaney's hearing began, Sen. Bernie Sanders (I-Vt.) was tweeting his concerns, suggesting Mulvaney's nomination meant Trump "doesn't intend to not cut Social Security, Medicare, or Medicaid":
