Trump decided a few weeks ago that he could help his prospects for re-election if he could get schools across the nation to reopen fully, regardless of the state of the pandemic in their community, regardless of the risks to students and staff. He has threatened to cut off federal funding to schools that refuse to reopen fully, and he proclaimed that he and Pence were pressuring the CDC to weaken its guidelines.

At first, the CDC held firm, urging schools to practice social distancing, to require personal protective equipment, and not to reopen unless all safety precautions were in place.

But the CDC buckled to the White House pressure. It changed the tone of its guidance, now stressing the necessity of reopening over the importance of safety.

Now the CDC sings the song that Trump, Pence, and DeVos want to hear.

The top U.S. public health agency issued a full-throated call to reopen schools in a package of new “resources and tools” posted on its website Thursday night that opened with a statement that sounded more like a political speech than a scientific document, listing numerous benefits for children of being in school and downplaying the potential health risks.

The Centers for Disease Control and Prevention published the new guidance two weeks after President Trump criticized its earlier recommendations on school reopenings as “very tough and expensive,” ramping up what had already been an anguished national debate over the question of how soon children should return to classrooms. As the president was criticizing the initial C.D.C. recommendations, a document from the agency surfaced that detailed the risks of reopening and the steps that districts were taking to minimize those risks [the document was incorrectly dated 2019].

“Reopening schools creates opportunity to invest in the education, well-being, and future of one of America’s greatest assets — our children — while taking every precaution to protect students, teachers, staff and all their families,” the new opening statement said.

The package of materials began with the opening statement, titled “The Importance of Reopening America’s Schools This Fall,” and repeatedly described children as being at low risk for being infected by or transmitting the coronavirus, even though the science on both aspects is far from settled.

“The best available evidence indicates if children become infected, they are far less likely to suffer severe symptoms,” the statement said. “At the same time, the harms attributed to closed schools on the social, emotional, and behavioral health, economic well-being, and academic achievement of children, in both the short- and long-term, are well-known and significant.”

While children infected by the virus are at low risk of becoming severely ill or dying, how often they become infected and how efficiently they spread the virus to others is not definitively known. Children in middle and high schools may also be at much higher risk of both than those under 10, according to some recent studies.

Beyond the statement, the package included decision tools and checklists for parents, guidance on mitigation measures for schools to take and other information that some epidemiologists described as helpful.

The new materials are meant to supplement guidance the C.D.C. previously issued on when and how to reopen schools, with recommendations such as keeping desks six feet apart and keeping children in one classroom all day instead of allowing them to move around.

The new statement released on Thursday is a stark departure from the 69-page document, obtained by The New York Times earlier this month, marked “For Internal Use Only,” which was intended for federal public health response teams to have as they are deployed to hot spots around the country.

That document classified as “highest risk” the full reopening of schools, and its suggestions for mitigating the risk of school reopenings would be expensive and difficult for many districts, like broad testing of students and faculty and contact tracing to find people exposed to an infected student or teacher.

An Associated Press/NORC poll this week found that most Americans said they were very or extremely concerned that reopening K-12 schools for in-person instruction would contribute to spreading the virus. Altogether, 80 percent of respondents said they were at least somewhat concerned, including more than three in five Republicans.

Thanks to Trump, the public can no longer trust the impartiality of the CDC. Under pressure, it revised its guidelines to please the president. Science will not “get in the way” of Trump’s political campaign. Any student or teacher or other school personnel who dies because of a premature opening will be blood on the hands of Trump, Pence, DeVos, and the CDC.

The CDC and its director, Dr. Robert Redfield, are hereby enrolled on the blog’s Wall of Shame.
