On Friday, the Oklahoma Supreme Court unanimously rejected a major move to protect it's people.
It was a bid to require attendees of Trump's Saturday rally to wear masks and practice social distancing.
"It is not the duty of this Court to fashion rules or regulations where none exist," the court wrote.
The ruling follows warnings from health experts who fear the rally could be a "superspreader" event.
The Oklahoma Supreme Court will not stand in the way of people who want to attend the rally maskless.
President Trump's rally will be in Tulsa tomorrow.
