President Donald Trump thinks schools should “absolutely open” in the fall, though his top health advisor for the coronavirus pandemic isn’t so sure.

National Institute of Allergy and Infectious Disease Director Anthony Fauci testified via livestream at a Senate committee hearing on Tuesday that there’s no “easy answer” to when schools should reopen to in-person classes.

“I mean, we just have to see on a step-by-step basis, as we get into the period of time with the fall about reopening schools, exactly where we will be in the dynamics of the outbreak,” he said.

On Wednesday, Trump said he doesn’t consider Fauci’s testimony an “acceptable answer” during a meeting at the White House with the governors of Colorado and North Dakota, USA Today reports.

“I think you should absolutely open the schools,” Trump said. “I don’t consider our country coming back if the schools are closed.”

The president said he was surprised by Fauci’s testimony Tuesday.

“To me, it’s not an acceptable answer especially when it comes to schools,” Trump said.

The president told Fox Business Network Fauci “is a very good person,” but he “totally” disagrees with him about reopening schools.

“We have to get the schools open,” Trump said. “We have to get our country open. … Now we want to do it safely, but we also want to do it as quickly as possible. We can’t keep going on like this. … You’re having bedlam already in the streets. You can’t do this. We have to get it open.”

Trump is far from the only one urging officials to reopen schools.

Kentucky Senator Rand Paul said he thinks “it’s a huge mistake not sending our kids back to school.”

Dimitri Christakis, director of the Center for Child Health, Behavior and Development at Seattle Children’s Hospital, recently penned a column for the journal JAMA Pediatrics that outlines how the lockdown is negatively impacting children’s learning, social-emotional development and mental health, NPR reports.

“The decision to close schools initially, and now to potentially keep them closed, isn’t, I think, taking the full measure of the impact this is going to have on children,” he told NPR. “Not just the short term, but the long term.”

According to recent research, students are expected to have made a third less progress in reading and half as much progress in math as a typical year when they return in the fall, but the lockdown is also taking a toll on students’ mental health and social-emotional development, Christakis wrote.

“The social-emotional needs of children to connect with other children in real time and space, whether it’s for physical activity, unstructured play or structured play, this is immensely important for young children in particular,” Christakis wrote.

Christakis, editor-in-chief of JAMA Pediatrics, pointed to a new study of children under lockdown in China that documents elevated depression and anxiety, as well as increases in child abuse during the pandemic as other important reasons to send kids back to class.

Unlike Fauci, Christakis seems to align more with President Trump’s take on reopening schools, framing the decision as an “imperative” rather than an option.

“I think we should sort of reason backwards from the expectation that children do start school, that that’s an imperative. And then how do we make that happen safely?” he wrote, suggesting a panel of interdisciplinary experts to devise a plan.
