Justice Sotomayor was appointed by President Obama in 2009. She’s been on the court for 15 years. She is the most senior Democratic appointee on the high court, followed by Justice Elena Kagan, who was also nominated by Mr. Obama, and Justice Ketanji Brown Jackson, who was nominated by Mr. Biden in 2022.
Democrats are still sour about the decision of liberal Justice Ruth Bader Ginsburg not to retire during a Democratic administration. She died in 2020, enabling Mr. Trump to appoint a justice — conservative Amy Coney Barrett — to a seat Ginsburg held for nearly three decades.
