President Trump said Thursday that “complainers” seeking greater amounts of coronavirus medical supplies “should have stocked up” before the crisis.

As cases surge, Trump’s administration deployed supplies from a federal strategic stockpile, used a wartime law to order companies to make masks and ventilators, and is taking donations from abroad.

On Twitter, Trump defended his performance with an attack on unnamed critics.

“Massive amounts of medical supplies, even hospitals and medical centers, are being delivered directly to states and hospitals by the Federal Government,” Trump wrote. “Some have insatiable appetites & are never satisfied (politics?). Remember, we are a backup for them.”

Trump added, “The complainers should have been stocked up and ready long before this crisis hit. Other states are thrilled with the job we have done. Sending many Ventilators today, with thousands being built. 51 large cargo planes coming in with medical supplies. Prefer sending directly to hospitals.”

Another Trump tweet on Thursday morning said Senate Minority Leader Chuck Schumer (D-NY) should “stop complaining & find out where all of these supplies are going.”

Nearly 210,000 US residents have been diagnosed with COVID-19 and more than 5,100 have died. New York is the nation’s epicenter with roughly 40 percent of cases.

The crisis has seen unusual bipartisan flattery between Trump and Democratic Gov. Gavin Newsom of California, but brutal barbs for Trump critics.

Trump last month called Washington state Gov. Jay Inslee, a Democrat, “a snake,” and tweeted against “Failing Michigan Governor” Gretchen Whitmer, also a Democrat.

This week, Whitmer and Maryland Republican Gov. Larry Hogan wrote a Washington Post op-ed critical of Trump, saying, “There simply aren’t enough test kits, medical supplies and other lifesaving equipment to meet the scope of this pandemic … the federal government must take extraordinary steps to deliver what we need.”
