Why are Trump and Musk being dishonest about social security fraud?

Social Security fraud

TRUMP: "We're also identifying shocking levels of incompetence and probable fraud in the Social Security program that our seniors and that our seniors, people that we love rely on, believe it or not, government databases list 4.7 million Social Security members, people aged 100 to 109 years old.”

Trump and his adviser Elon Musk have both claimed, without evidence, that there is rampant fraud in the Social Security system. In his remarks, Trump asserted that government databases list millions of people aged well over 100 years old, including 1.3 million people between 150 to 159 years old and over 130,000 people aged over 160.

But a 2023 report from the Social Security Administration's Office of the Inspector General said that there were nearly 19 million Social Security number-holders aged 100-plus who didn't have information about their deaths in the system and that "almost none of the 18.9 million number-holders currently receive SSA payments."

The SSA's acting commissioner, Leland Dudek, has also knocked down these claims.
