Hinojosa said the Dallas ISD mandate will remain in place for the safety of teachers and students, until a court specifically orders the district to stop. His decision is getting the recognition of President Joe Biden as well.

“[Biden] thanked me for having the courage for our students and the community,” Hinojosa said.

He said if he loses his legal battle, then the district he will offer virtual school. That could cost the district $100 million out of its own pocket, but he said he’s ready for a fight.
