While President-elect Trump is promising to slash unnecessary government spending in his next term, questions are emerging about how the 47th president might approach Social Security — the biggest chunk of the U.S. budget that is barreling toward bankruptcy. 

The Congressional Budget Office estimates that without significant intervention, the Social Security trust funds are due to run dry in 2033, at which point the law calls for a 23 percent cut in benefits. 

Trump’s proposals to lower corporate tax rates, end taxes on tips, Social Security benefits, and overtime pay, and deduct car loan interest and state and local taxes could add $2.3 trillion to Social Security’s cash deficit, according to the Committee for a Responsible Federal Budget, a non-partisan organizaton. The committee says these proposals could increase the $35 trillion national debt by $7.75 trillion through 2035.

With the formation of the Department of Government Efficiency, or DOGE, led by Tesla chief executive Elon Musk and entrepreneur Vivek Ramaswamy, Trump has signaled his intention to tackle America’s spending problem. While DOGE will work to “slash excess regulations, cut wasteful expenditures, and restructure Federal Agencies,” Trump also has said he would “fight for and protect Social Security.”
