On May 10, 2010, President Barack Obama announced his selection of Elena Kagan for Associate Justice of the Supreme Court of the United States, to replace retiring Justice John Paul Stevens. Kagan's nomination was confirmed by a 63–37 vote of the United States Senate on August 5, 2010.
When nominated, Kagan was Solicitor General of the United States, to which she had been appointed by Barack Obama. She had previously been a contender for the retiring David Souter's seat in 2009, but was passed over in favor of current Supreme Court Justice Sonia Sotomayor.
Prior to her reported selection as Obama's nominee, Kagan had been appointed as Solicitor General of the United States. In May 2009, she was widely speculated to be a nominee acceptable to fill the seat of retiring Supreme Court Justice David Souter. The seat was eventually filled by Judge Sonia Sotomayor of the Second Circuit.
In the Senate, Kagan's nomination was received positively by most Democrats, who praised her abilities and the fact that she came from outside the so-called 'judicial monastery' . Republicans were quicker to express criticism, particularly over her handling of military recruiters during her time as Dean of Harvard Law School, as well as her work as a law clerk for the late Justice Thurgood Marshall, whom many of them deemed a liberal activist.
The deans of over one-third of the country's law schools, 69 people in total, endorsed Elena Kagan's nomination in an open letter in early June. The letter lauded what it considered her coalition-building skills and "understanding of both doctrine and policy" as well as her written record of legal analysis.
