HOUSTON Harris County Judge Lina Hidalgo is set to provide an update Monday on how schools in Harris County will be allowed to reopen classrooms. The health authorities in both Harris County and Houston signed a joint order in late July that shuttered schools to in-person instruction until at least Sept. 8. That order was thrown into question after the states attorney general said he doesnt believe local officials have the authority to keep schools closed. Hidalgos news conference is scheduled to begin at 11 a.m. Click2Houston.com plans to offer a livestream of the event. This story will be updated.
