"Today we mark a truly grim, heartbreaking milestone-5,00,071 deaths. That's more Americans who have died in one year in this pandemic than in World War One, World War Two and the Vietnam War combined," Biden said his remarks during a ceremony to commemorate dead the grim milestone of more than 500,000 deaths due to COVID-19 urging Americans to set aside partisan differences and fight the pandemic together.

The US President led the moment of silence on Monday around 6:15 EST outdoors at the White House.

A military band played a soaring rendition of "Amazing graze" and five hundred lit candles were lined at the White House steps.

All the federal properties and military facilities will be lowering flags to half-staff until Friday at the sunset.

Biden urged people to end the politics and misinformation "that has divided families, communities and the country, and has cost too many lives already." He added, "It's not Democrats and Republicans who are dying from the virus. It's our fellow Americans."

The United States has seen more than 19% of total COVID-19 deaths. 4% of the world population died due to the pandemic.

The country's overall death figures have been blamed upon former president Donald Trump. Joe Biden won the elections in November 2020 partly due to his promise that he will be handling the pandemic better.
