Final answer:
President Obama appointed Justice Sonia Sotomayor in 2009 and Justice Elena Kagan in 2010 to the Supreme Court, both of whom are known for their liberal rulings.
Step-by-step explanation:
During President Obama's first term, two women were placed on the Supreme Court: Justice Sonia Sotomayor in 2009 and Justice Elena Kagan in 2010. Both justices have served on the Supreme Court with rulings that align with a more liberal ideology, reflecting President Obama's own viewpoints. These appointments also demonstrated Obama's commitment to diversity on the Court and were significant in that they took place while the Democratic Party controlled the Senate, helping guarantee their confirmations.
