Trump can say whatever he want, but as of now I am skeptical whether there would be a rebound in the economy by September. A rebound may only occur if the pandemic can be contained. And under current circumstances, it is impossible to contain the pandemic unless a vaccine is made available. And all that is going to take a long time. And let's not forget the fact that the US federal debt is at a historical peak. That further reduces Trump's maneuvering space.
