WASHINGTON - Supreme Court nominee Amy Coney Barrett will return to Capitol Hill Wednesday for the third day of confirmation hearings by the Senate Judiciary Committee — set to be her last session following hours of testimony this week.Barrett has vowed to bring no personal agenda to the high court but decide cases “as they come.” She has remained neutral on many issues, asserting that she could not say whether she would overturn the Affordable Care Act or how she would vote on other politically fraught issues, including abortion.In testimony on Tuesday, Barrett answered questions from the 22 senators on the committee — each getting 30 minutes.
