Former professional wrestling exec and billionaire GOP donor Linda McMahon faced tough questioning—and scattered protests—on Thursday during her confirmation hearing to head an Education Department that President Donald Trump is keen on abolishing.

During two-and-a-half hours of questioning (and opining) by senators, McMahon attempted to thread the needle between Trump’s plans to gut the 45-year-old US Department of Education and federal laws and constitutional guardrails that stand in his (and Elon Musk’s) way. Even as she expressed support for key Trump policies—including private-school voucher programs and bans on trans girls and women from sports—McMahon’s scant experience in education was on display as she misstated, or failed to answer key questions about, federal education law.
