The Bureau of Prisons said Monday that it's resuming in-person visits at all 122 of its facilities, according to an internal memo obtained by ABC News.

"Social visiting will resume no later than Saturday, October 3, 2020," the memo said, adding that visiting will be non-contact only.

"Use of Plexiglas or a similar barrier between inmate and visitors will prevent any contact. In the alternative, if a barrier is not present, social distancing (i.e., 6 feet apart) between visitors and inmates must be enforced," the memo said.

Inmates and visitors must wear face coverings at all times.

Every inmate will be permitted two visits per month. Inmates in isolation or quarantine will not be allowed visits.

Dr. Anthony Fauci, the nation's top medical expert on the coronavirus pandemic and a key member of the White House coronavirus task force, is weighing in on comments President Donald Trump made during a recent interview with Fox News.

Speaking to Fox News’ Laura Ingraham on Monday, Trump said he "inherited" Fauci, who is the director of the National Institute of Allergy and Infectious Diseases, and that he disagrees with “a lot” of what he says.

"I think when you get statements like that, that doesn’t really reflect what goes on," Fauci told ABC News' Amy Robach in an interview Tuesday on "Good Morning America." "I think that’s kind of a distraction to pit me against the president. We’re all on the same team."

Fauci also attempted to clarify new information released by the U.S. Centers for Disease Control and Prevention, which showed 94% of those who died from COVID-19 as of last week had underlying health conditions and contributing causes.

"The point the CDC was trying to make was that a certain percentage of them had nothing else but just COVID. That does not mean that someone who has hypertension or diabetes who dies of COVID didn’t die of COVID-19. They did," he said. "So the numbers that you’ve been hearing, the 180,000 plus deaths, are real deaths from COVID-19."

Trump, however, retweeted a conspiracy theory that suggested only 9,000 people have died from COVID-19 in the United States -- the original tweet has since been removed by Twitter.

"Let there not be any confusion about that. It’s not 9,000 deaths from COVID-19; it’s 180,000 plus deaths," Fauci added.

When asked about the CDC’s new guidelines on COVID-19 testing, Fauci admitted, "That did create some confusion."

"The way that sentence was said, it gave the impression that they’re not concerned about community spread and that people who are asymptomatic should not be tested," he said. "There’s no doubt that there are asymptomatic infection and that asymptomatic people can transmit and that you can and should test asymptomatic people."

"What the guideline was trying to do was to try to make the point that not everyone who wants to be tested should be tested; only if you need to be tested," he continued. "Understandably, that was confusing. Hopefully, that’s been straightened out now."

Arizona State University said it now has 803 known cases of COVID-19 among its students and staff.

Since Aug. 1, the public research university has collected test results from 40,402 students and employees so far. As of Sunday, 775 students and 28 staff and faculty members had tested positive for COVID-19. All positive cases are in isolation, according to the school.

"It is our expectation that COVID-19 is not going away anytime soon and that we must find a way to operate the university in a way that accounts for the ongoing presence of the virus," Arizona State University said in an update posted on its website Monday night. "The incidence of testing has increased as we launched periodic testing of a statistically significant percentage of the on-campus population. ASU maintains a low positivity rate with students and an even lower positivity rate with faculty and staff."

Most of the cases -- 428 -- were among people living off campus in the metropolitan Phoenix area. Another 323 are in isolation on the Tempe campus, where a total of 9,645 students live. The remaining are in isolation on either the downtown Phoenix or West campuses, where a collective total of 1,717 students live.

The university said there are currently no known cases at the Polytechnic campus, where 757 students live.

Russia has recorded 4,729 new cases of COVID-19 and 123 related deaths over the past 24 hours, the country’s coronavirus response headquarters said Tuesday morning.

The nation’s cumulative total now stands at 1,000,048 confirmed cases with 17,299 deaths.

Russia is the fourth country in the world to reach the 1 million mark of COVID-19 diagnoses, after the United States, Brazil and India, according to data from Johns Hopkins University.

The start of in-person learning in New York City public schools has been delayed to Sept. 21, Mayor Bill de Blasio announced Tuesday.

The district's blended-learning plan was scheduled to begin on Sept. 10.

"Teachers who usually get two days of professional development at the beginning of the school year will now get nine," schools Chancellor Richard Carranza said. "We've heard from everyone in our schools that have said we need some more time."

In averting a strike authorization vote by the United Federation of Teachers later Tuesday, de Blasio agreed to delay the start of school to Sept. 16 for all-remote instruction. In-person learning, which is limited to a few days per week, will begin Sept. 21.

The mayor also announced expanded testing for teachers, a significant concession to the United Federation of Teachers.
