This is an old program.
Student Loan forgiveness if your VA rating is 100% has been around for at least 10 years, as that's when I first ran across it. Like so many VA benefits, it's not widely understood, nor is it easy to apply for and get. The EO Trump signed didn't add to the program, it just directed that the application processes be made easier and faster so folks can actually apply for and get the existing benefit.
