Which Supreme Court Justice was appointed by President Barack Obama?

The correct answer highlights that both Sonia Sotomayor and Elena Kagan were appointed to the Supreme Court by President Barack Obama. Sonia Sotomayor was nominated in 2009 and became the first Hispanic and Latina member of the Court, while Elena Kagan was nominated in 2010 and became the fourth woman to serve on the Court. This underscores President Obama's commitment to diversity and representation in the judiciary, marking a significant shift in the Court's composition during his administration.

Stephen Breyer, while also a notable member of the Supreme Court, was appointed by President Bill Clinton and not by Obama. Understanding the significance of these appointments helps clarify their impact on the Court's decisions and the broader legal landscape in the United States.
