School bus driver shortages affecting families across the country

School bus driver shortages are having a ripple effect on schools, students and families across the country – and have already forced schools in at least nine states to request assistance from the National Guard.

Among them is Maryland, where some schools in the biggest district have been forced to return to remote learning, Errol Barnett reports for "CBS Saturday Morning." It's been more than two weeks since the district sent its own SOS. They asked for 200 bus drivers, said Earl Stoddard, Montgomery County's assistant chief administrative officer.

"They are still inclined to try and help us, but they're looking for resources to do it," he said.
