White House press secretary Jen Psaki on Monday said President Biden wants to see schools open, citing the mental health implications on children, as Chicago Public Schools closed for a fourth day.

“We have been very clear publicly and privately that we want to see schools open,” Psaki said when asked what the White House’s message is to the teachers union that forced the closure and Chicago Mayor Lori Lightfoot (D) on what it wants to see in the coming days.
