Trump: vaccine or no vaccine, America is back

In comments made in a White House Rose Garden press briefing, Trump unveiled what he called "Operation Warp Speed," an initiative bringing together academia, scientists, corporate America and the military to fast-track the discovery and manufacture of a vaccine for widespread use by the end of the year.

A bellicose Trump said with or without a vaccine - America was back and even though it would help global partners in finding a vaccine, he was prepared to use the full might of America's resources to take the lead.
