Dr. Fauci then said that if schools were to prematurely reopen, there is then a risk of going backward in progress, and they could end up seeing the death toll, and number of cases beginning to increase again.
"I was surprised by his answer, actually, because, you know, it's just to me it's not an acceptable answer especially when it comes to schools", Mr. Trump said during a meeting with Colorado and North Dakota leaders in the White House's Cabinet Room.
Trump's relationship with Fauci has been closely scrutinized during the coronavirus outbreak because he sometimes appears to contradict or correct the President during public appearances.
Fauci is due to appear before the Senate, as Donald Trump encourages businesses across the USA to reopen.
Fauci himself is in self-quarantine as he may have come into contact with either of two White House staff members who were diagnosed with COVID-19.
The New York Times reported that Fauci will deliver a stark warning of the dangers of lifting restrictions in the USA too soon.
Trump and Fauci have publicly disagreed before, including on the effectiveness of certain drugs that have been tested to treat the virus. Paul, who dismissed the scientist's conclusions, said, "I don't think you're the end-all".

"But in other parts of the country, we are seeing spikes", Fauci said.
"Anthony is a good person, a very good person, I've disagreed with him", Trump said in an interview earlier on Wednesday with Fox Business Network's "Mornings with Maria", repeating his refrain that the country must reopen.
Dr Fauci referred to a rare inflammatory syndrome believed to be linked to the novel coronavirus, which has killed at least three children in NY and afflicted dozens of others. He recommended that the states should follow the administration's guidelines for safely reopening, which includes criteria that need to be satisfied before easing restrictions.
