President Barack Obama on Monday announced the nomination of Rabbi David Nathan Saperstein to be the ambassador at large for international religious freedom at the State Department, a position that has been vacant since late last year.

“I am grateful that Rabbi Saperstein has chosen to dedicate his talent to serving the American people at this important time for our country,” Obama said. “I look forward to working with him in the months and years ahead.”

Saperstein is director and counsel at the Religious Action Center of Reform Judaism, and teaches First Amendment church-state law and Jewish law at Georgetown University.

Rep. Frank Wolf (R-Va.), who has warned about violence against Christians taking place in Iraq, welcomed Saperstein’s nomination and called on the Senate to quickly confirm him.

“Rabbi Saperstein is well-respected on these matters, and has been engaged on this issue for a long time,” Wolf said on the House floor.

“I welcome this nomination. It is a good nomination, and I ask the Senate to confirm Rabbi Saperstein quickly.”

Wolf said the U.S. needs to do more to protect Christians in Iraq from violence, persecution and what he said amounts to genocide in that country.

“The churches have been seized, and some turned into mosques,” Wolf said. “Every trace of Christianity is being eradicated in Iraq.”
