Trump's education chief Linda McMahon comes from boardroom, not classroom. Backers say that's her strength

Linda McMahon is nominated as the next US Education Secretary. President Trump plans to dismantle the Education Department. McMahon's private-sector experience is seen as an asset. Democrats oppose the plan and question her qualifications. McMahon previously led the Small Business Administration and has limited experience in education. Her confirmation hearing is expected to be contentious.
