The total number of people who are confirmed to have contracted the virus reached more than one million on Tuesday, while the country’s death toll stood at 58,317, according to data from Johns Hopkins University.
The figures, which represent Washington’s handling of the virus during the three months of the outbreak, come as only 58,220 Americans were killed over two decades in Vietnam.
Nearly 17,000 US troops lost their lives during the war's deadliest year in 1968.
Asked whether a president deserves re-election if more American lives have been lost within six weeks than during the Vietnam War, Donald Trump said during a White House briefing on Monday that the US has "lost a lot of people" but "original projections" had initially predicted more than two million deaths.
"We're probably heading to 60,000, 70,000," he said. "One person is far too many for this."
Trump has frequently compared himself to a "wartime" president facing an "invisible enemy" during the public health crisis.
Trump is under fire for publicly downplaying the threat of the pandemic when it broke out in the US in late February, and his handling of the COVID-19 crisis.
The US president claimed at the time that coronavirus cases would soon “be down to close to zero,” and did not declare a national emergency over the pandemic until the end of March, as virus cases were on the rise in New York and the stock market nosedived.
Since the flu-like pathogen broke out in the Chinese city of Wuhan in late December, Beijing and Washington have time and again clashed over the virus spread, further increasing tensions between the world's two largest economies.
Trump keeps referring to the novel coronavirus, which causes a respiratory disease known as COVID-19, as the Chinese virus. Beijing has hit back by suggesting that the US military brought the virus to Wuhan and initiated the outbreak.
The virus has so far infected over 3,136,000 people worldwide. Nearly 218,000 have died, according to a running count by worldometers.info.
