Progressives responded with a mixture of alarm and ridicule to news that President Donald Trump is planning later this week to sign an executive order to “protect” Medicare, a government-run program, from “socialist destruction.”

The Washington Post reported that the executive order, which Trump is set to unveil Thursday during a trip to Florida, is part of a concerted attack on the push for Medicare for All, a proposal championed by Sen. Bernie Sanders (I-Vt.) and backed by Sen. Elizabeth Warren (D-Mass.).

Observers said Trump’s planned executive order is reminiscent of the infamous “keep your government hands off my Medicare” line that was shouted at a Republican lawmaker during a town hall in 2009, in the heat of the fight over the Affordable Care Act.

“I understand why people like Trump and [Vice President Joe] Biden try to scare old people about Medicare for All. Scaring old people is time-tested!” HuffPost reporter Jeffrey Young tweeted Sunday. “But the idea that giving government healthcare to everyone somehow means taking it from people who already have government healthcare is just absurd.”
