The Trump administration, state officials and even individual hospital workers are now racing against each other to get the necessary masks, gloves and other safety equipment to fight coronavirus — a scramble that hospitals and doctors say has come too late and left them at risk. But according to a previously unrevealed White House playbook, the government should’ve begun a federal-wide effort to procure that personal protective equipment at least two months ago.The strategies are among hundreds of tactics and key policy decisions laid out in a 69-page National Security Council playbook on fighting pandemics, which POLITICO is detailing for the first time. Other recommendations include that the government move swiftly to fully detect potential outbreaks, secure supplemental funding and consider invoking the Defense Production Act — all steps in which the Trump administration lagged behind the timeline laid out in the playbook.https://www.politico.com/news/2020/03/25/trump-cor...

Stop lying he said he hopes not that he will

He's ambitious, that's his nature. But I don't see it happening. 

It’s possible with a full shut down of the country until then.
