Multiple Democratic presidential contenders piled on Sen. Elizabeth Warren (D-Mass.) during the Oct. 15 presidential debate.
Warren has refused to say that taxes would go up for the middle class under Medicare for All. She has endorsed a bill written by Sen. Bernie Sanders (I-Vt.), who has said multiple times his plan would require higher taxes.
