Virginia Gov. Bob McDonnell has vetoed a measure passed by the General Assembly that would require 150 minutes of physical education per week for K-8 students starting in 2014 — legislation that was opposed by school and government groups who, like McDonnell, maintained that it would place an undue burden on localities.

“While I strongly agree that we must encourage exercise and physical activity, I oppose unfunded mandates, whether they come from Washington or Richmond,” McDonnell said.
