Republican presidential front-runner Donald Trump said he and his rich pals should “voluntarily” forgo their Social Security benefits to bolster the health of the retiree entitlement system, declaring “I don’t need mine, by the way.”

At a multi-candidate presidential forum in New Hampshire on Monday, Mr. Trump said that for the good of the country, rich taxpayers should sacrifice the benefits from the entitlement system into which they had paid throughout their professional lives.

“I have friends that are worth hundreds of millions and billions of dollars and get Social Security. They don’t even know the check comes in,” said Mr. Trump at the nonpartisan No Labels forum.

The real-estate developer and reality television star, who says he is worth $10 billion, said he would forgo the $400,000 presidential salary if elected.
