A federal program designed to cancel student loans for certain public workers has largely failed to deliver on that promise.
  
Republicans want to end it. Democrats want to fix it.
  
The program, called Public Service Loan Forgiveness, promises to erase federal student loans for public workers who make 10 years of payments while working for approved employers. It's meant to help teachers, military members and others who work in public service.
  
But complex rules have made it difficult to qualify, and 99% of applicants have been rejected.
  
The Trump administration and some Republicans have called for an end to the program, saying it has proved too confusing for borrowers to navigate. But Democrats want to overhaul and expand the program, saying the Education Department has failed to implement it properly.
