Sen. Jon Kyl (R-Ariz.) said today he will not vote to confirm Sonia Sotomayor's nomination to the Supreme Court. The Senate is set to vote on her confirmation this week after the Judiciary Committee approved her nomination July 28.

"For 220 years, presidents have sought out judges and justices who fulfill the requirement that they put aside any personal opinions and apply appropriate U.S. law to impartially resolve disputes," Kyl wrote in a long statement. "I have not been persuaded that Judge Sotomayor will uphold this important tradition. For these reasons, and others, I will oppose her confirmation."

Kyl, a member of the Senate Judiciary Committee, first announced his opposition to Sotomayor's nomination July 22. Just one Republican on the committee, Lindsey Graham of South Carolina, voted to send her nomination to the floor of the Senate.

Kyl said Sotomayor's judicial record gives him "reason to believe she will not set aside her own personal biases when deciding a case."
