The US recorded the highest number of coronavirus deaths in a single day with more than 1,800 fatalities reported on Tuesday.
It brings the total number of deaths in the country to nearly 13,000, according to data from Johns Hopkins University.
The US has more than 402,000 confirmed cases, the highest number in the world. Global cases have exceeded 1.4 million.
During a press conference on Tuesday, Mr Trump said the US might be getting to the top of the "curve" but was reluctant to discuss further, saying that the US might be on track for fewer deaths than projected.
The new figures announced on Tuesday are up on the previous record of 1,344 which was recorded on 4 April.
But a revised forecast released on Wednesday by the University of Washington has predicted a lower total death count in the US, estimating that around 60,000 Americans could die from Covid-19.
Donald Trump criticises WHO
Meanwhile, Mr Trump has attacked the World Health Organization (WHO), saying it had issued bad advice and had been too focused on China.
"The WHO really blew it. For some reason, funded largely by the United States, yet very China centric," he said.
Trump also said the US would be withholding money meant for the WHO.
The United Nations Secretary General Antonio Guterres addressed Mr Trump's comments through a spokesman on Wednesday.
"The World Health Organization must be supported as it is absolutely critical to the world's efforts to win the war against Covid-19," the spokesman said.
The spokesperson said that once the world finally turns the page on this epidemic, it will be a time to look back and fully understand how such a disease emerged and spread its devastation so quickly across the globe, and how all those involved reacted to the crisis.
Meanwhile the city of Wuhan in China, where the infection first emerged, ended its 11-week lockdown with a celebration.
