Determined to reopen America’s schools despite coronavirus worries, President Donald Trump threatened on Wednesday to hold back federal money if school districts don’t bring their students back in the fall.

Despite Trump’s increased pressure on state and local officials, New York City announced that most of its students would return to classrooms only two or three days a week and would learn online in between.

Germany did begin to reopen its schools in May, but in many cases students are taking turns going to school and studying at home for half the week — just the thing that administration officials have criticized.

Trump made his threat a day after launching an all-out effort pressing state and local officials to reopen the nation’s schools and colleges this fall.

At a White House event Tuesday, health and education officials argued that keeping students out for the fall semester would pose greater health risks than any tied to the coronavirus.

At the task force briefing, and a day earlier in a call with the nation’s governors, Education Secretary Betsy DeVos said anything less than a full reopening would be a failure for students and taxpayers

But some of the nation’s largest districts plan to bring back limited numbers of students for only a few days a week, saying it would be unsafe for all to return at once

DeVos singled out Virginia’s Fairfax County Public Schools, which are asking families to decide between fully remote instruction or two days a week at school

In announcing New York City’s plan for in-person instruction two or three days a week, de Blasio said schools can’t accommodate all their students at any one time while maintaining social distancing

The city’s public school system, with 1.1 million students, is by far the nation’s largest
