The Social Security Administration is facing a funding cliff that could be accelerated by Trump's economic proposals, a think-tank says.

Former President Donald Trump has long vowed to protect Social Security. But the bevy of tax breaks he’s promised – including pledging to stop taxing Social Security benefits – could hasten the depletion of the beloved entitlement program’s trust funds and leave seniors with smaller monthly payments.

Without Congressional and Presidential action to raise revenues, benefits would be immediately reduced by 23 percent Under Trump's plan benefits will fall by 33 percent.
