It is 4th of July, the Independence day for the Americans. An important festival that has always been celebrated with great pomp. But this year there is the pandemic, which is particularly serious in the United States, and the health authorities have been advised to avoid gatherings. President Donald Trump, however, will not lead by example. Tonight he will speak to the nation from the White House and then the fireworks show will begin, which will attract thousands of people to the National Mall.
