As it happened: Coronavirus - Trump praises 'incredible' Boris Johnson's recovery - BBC News
President Trump said the British premier showed "tremendous energy, tremendous drive".
The harsh political reality for the president is he faces a re-election contest in just over six months, and the longer the lockdown drags on, the less time the economy will have to recover before voters head to the ballot box.

Current polling suggests he is trailing presumptive Democratic nominee Joe Biden nationally and in key battleground states, and while the race is likely to tighten and the president has abundant resources to run a robust campaign, Trump appears destined for an uphill fight.

The president also faces a flip-side risk of being seen as supporting re-opening too quickly and shouldering the blame if there is a subsequent spike in cases. That could explain why, just days after calling for states to begin reopening process, he criticised the Republican governor of Georgia for lifting restrictions on places like hair salons, bars and tattoo parlours, where social distancing guidelines would be difficult to follow.

It's a difficult line for any politician to walk, and in the days ahead the stakes will be at their highest.
