According to data published by the World Health Organisation, Friday was America's deadliest day since the Covid-19 pandemic hit America.
According to the figures, the US recorded 2,909 deaths in a single day as of 4am on Friday, the Daily Mail reported.
So far, that number is the highest daily Covid-19 death toll America has seen.
It substantially surpasses the second highest US daily death toll, on April 23, when 2,471 deaths were reported.
At least 67,173 people have died as a result of coronavirus in the US, where there have been more than 1.1 million confirmed cases.
Over the past fortnight, several states have started reopening stores, restaurants and other public spaces.
The data released by the WHO is different from the figures collected by the US Centres for Disease Control and Prevention (CDC).
According to CDC data, 2,349 people died across America on May 1.
However, the CDC did acknowledge that it doesn't know the "exact number" of illnesses, hospitalisations and deaths related to coronavirus in the US.
The United States, with the world's third-largest population, has five times as many cases as the next hardest-hit countries of Italy, Spain and France.
Federal guidelines call for the number of cases to fall for 14 straight days before relaxing lockdown measures, but Texas and several other US states have forged ahead with reopening regardless.
Texas began relaxing coronavirus lockdown measures on Friday despite reporting the single-day high in deaths.
Stores, restaurants, movie theaters, malls, museums and libraries were allowed to reopen but with limited occupancy - just 25 per cent of their capacity.
Public swimming pools, bars, gyms, beauty salons, massage parlors, bowling alleys, video game arcades and tattoo shops remain closed.
And Texas Governor Greg Abbott sounded a note of caution, tweeting that 'Texans should continue to practice social distancing' and follow health guidelines.
'Face coverings are not mandatory, but encouraged to protect the lives of individuals at high-risk,' Abbott said.
President Donald Trump, with the election just six months away and the economy in a shambles, has sent mixed messages about the reopening of the country.
He has promoted the guidelines - while at the same time expressing support for protests in several states demanding a faster easing of stay-at-home orders.
In California, Governor Gavin Newsom reversed an order allowing some beaches to open after they were packed last weekend.
While Newsom was re-closing beaches, New York Governor Andrew Cuomo announced that schools in New York state, the epicenter of the US outbreak, would stay closed for the rest of the academic year.
The number of cases has been on the decline in some of the hardest-hit states such as New York and New Jersey.
But the daily count of new cases nationwide has been holding steady at nearly 30,000.
