The Senate voted Wednesday to confirm a prominent Catholic law professor to a high-ranking State Department position.

By a margin of 49 to 44, Robert Destro, a law professor at Catholic University of America's Columbus School of Law, was confirmed by the Senate as the next Assistant Secretary of State for Democracy, Human Rights, and Labor. Sen. Susan Collins (R-Maine) joined Democrats in opposition to Destro's confirmation.

"Robert Destro is one of the nation's experts on human rights, both in terms of international law and the moral basis for human rights," Thomas Farr, president of the Religious Freedom Institute, told CNA in a statement, noting Destro's experience both as a human rights scholar and activist "in the best sense of that term."

Destro's new role at the State Department is tasked with promoting democracy, civic and religious freedom around the world.

It "is the senior human rights position in American diplomacy," Farr said, charged with promoting human rights "not simply as the right thing to do (which it is), but also as a strategic interest of the United States."

"Destro will excel in both tasks," Farr said.

Destro is the founding director of the Interdisciplinary Program in Law & Religion at Catholic University; he previously served as a Commissioner on the U.S. Commission on Civil Rights from 1983 to 1989, addressing issues of discrimination on the basis of disability, national origin, and religion.

He has also served on the State Department's Working Group on Religion in Foreign Affairs, as well as the special counsel for voting rights for the Ohio Secretary of State from 2004 to 2006.

Catholic University president John Garvey welcomed Destro's confirmation, calling him "one of the most treasured members of our law school faculty."

"This appointment is a unique opportunity for Bob to work at the highest levels of our nation's government to protect the freedoms of all people, and in particular of those on the margins of societies around the globe," Garvey said. 

"I have no doubt that he will serve our nation as he served Catholic University, with great skill and dedication."

Stephen C. Payne, dean of Catholic's law school, said he was "thrilled" by the appointment, and that in Destro the "country -- and the rest of the world -- is getting a strong advocate and leader for Democracy and Human Rights, and we wish him well."

The appointment was also welcomed by Toufic Baaklini, president of the group In Defense of Christians (IDC), who cited Destro's years of work with the group and called him "a critical leader in the fight for genocide recognition for victims of ISIS in Iraq and Syria" and "a powerful voice for religious freedom in the Middle East, and throughout the world."

Senate Democrats questioned Destro at his confirmation hearing in March over the role of religion in foreign affairs as well as the redefinition of marriage.

Destro said that he would work to improve both training on religious freedom and understanding of the role of religion in foreign affairs within the State Department, and cited his own past work bringing various religious groups together on the international stage.

Destro said that he had learned from "the many years that I have been dealing with the State Department" that many at the agency "have had a hard time dealing with the issue of religion, and that's one of the issues I'd like to bring to their attention."

Later in the hearing, he explained that the Frank R. Wolf International Religious Freedom Act of 2016-authored by Rep. Chris Smith (R-N.J.) and signed into law by President Obama-required religious freedom training for all foreign service officers.

Destro said he would work to expand on that, saying that "not only do the foreign service officers need to be trained, but so do the lawyers at the State Department and at USAID."

"I think that we need to bring people together, and I've devoted most of my career, for at least the last 16 years, to doing just that," he said of bringing religious groups together.
