 And now to the United States, where President Joe Biden has celebrated the nation's 245th birthday by opening the doors of the White House and calling on Americans to do their parts to end the COVID-19 pandemic once and for all. Biden told the White House party, open to around 1,000 people, including military families and workers involved in the COVID-19 response. Now the largest White House event since Biden took office in January included burgers and fireworks and was geared towards giving Americans something to celebrate as signs of normalcy have returned following a coronavirus pandemic that has killed more than 600,000 Americans.
