North Dakota State University has lifted its evacuation order.
The university ordered all students and employees to leave campus Monday morning after it received a bomb threat.
The University of Texas, meanwhile, says all university buildings have been cleared and are reopening after a bomb threat prompted an evacuation of the Austin campus.
The school had issued and alert shortly before 10 a.m. telling people to immediately evacuate all campus buildings and "get as far away as possible" after the school received a phoned-in bomb threat.
The FBI says it's trying to determine if the two threats were related.
