Rabbi David Saperstein will deliver an invocation at the Democratic National Convention. The director of the Religious Action Center of Reform Judaism will deliver the invocation on Aug. 28, the night that Sen. Barack Obama (D-Ill.) is scheduled to accept the Democratic nomination. "I am deeply honored to have been invited to offer a religious voice at this celebration of American democracy; the opportunity to do so at an evening of such historic significance to our nation is especially meaningful," Saperstein said. The Democratic convention will open with a public interfaith service of Christians, Jews, Muslims and Buddhists. Several prominent religious leaders, including the heads of several Jewish, Christian and Muslim denominations and national organizations, are participating in both the Democratic and Republican National Conventions. US Rep. Robert Wexler (D.-Fla.) will also speak at the convention, on foreign policy issues. The Jewish congressman represents a large Jewish constituency.
