CNA STAFF (CNA) -- EWTN Global Catholic Network, the world’s largest Catholic media organization, announced Friday that Andrew Walther – an experienced Catholic journalist, media executive, and advocate for persecuted Christians – has been named president and chief operating officer of EWTN News, Inc. The appointment is effective June 1.

Walther began his Catholic media career as a journalist writing for the National Catholic Register two decades ago. Most recently he has served as vice president for communications and strategic planning at the Knights of Columbus.

In his role as president of the news division, Walther will oversee EWTN’s vast news media platforms, which create content in English, Spanish, German, French, Portuguese and Italian. Its holdings include Catholic News Agency, the National Catholic Register, the ACI Group, ChurchPop and EWTN’s lineup of television and radio news programming.

“As well as being an accomplished Catholic journalist and media executive, Andrew Walther brings to this role unique expertise in the global Church,” said EWTN Chairman and CEO Michael P. Warsaw.

“His leadership experience with a global Catholic communications and media operation – and his previous work with the National Catholic Register and EWTN News Nightly – gives him the added advantage of already knowing the Catholic media world and many of the people within the EWTN family. We look forward to having him lead and strengthen our news division,” Warsaw said.

Since 2005, Walther has worked in senior roles at the Knights of Columbus. During his tenure at the Knights, Walther helped launch the organization’s modern communications department, overseeing work with Catholic and secular media outlets, the launch of social media channels and video production, and the organization’s global media work, especially in Europe and the Middle East. He was also heavily involved in the organization’s charitable work and disaster relief initiatives.

Walther also organized and led the Knights’ work on behalf of persecuted Christians in the Middle East, traveling to Iraq several times and successfully leading a public effort to have ISIS’ campaign of persecution declared  a genocide by Secretary of State John Kerry.

His advocacy for persecuted Christians and other religious minorities in the Middle East helped shape policy in both the Obama and Trump administrations, and he also helped play a role in forging a bipartisan legislative consensus on behalf of persecuted Christians and other victims of ISIS in the Middle East. Walther’s efforts included working with other governments and the UN as well as with Catholic, Orthodox, Protestant, Jewish and Muslim leaders to end violence and persecution and bring relief to persecuted Christian communities.

“Andrew Walther has been a good friend and a trusted colleague for many years,” said Archbishop José H. Gomez of Los Angeles, who is president of the U.S bishop’s conference and a longtime member of EWTN’s board of governors.

“Andrew is one of the Church’s finest strategic thinkers and a highly respected advocate for international religious liberty. All of this will serve him well as head of the world’s largest Catholic news organization. I wish him great success.”

While working closely over the years with many bishops, dioceses and Catholic organizations in North America, Walther also worked closely with the Vatican on several projects under both Pope Benedict XVI and Pope Francis.

“Mother Angelica created a network dedicated to ‘the advancement of truth’ and Catholic news is a vital part of this mission,” Walther said Friday.

“I look forward to working with the talented and dedicated team of journalists at EWTN News to provide news from a Catholic perspective and to highlight important stories that might otherwise be overlooked.”

In addition to his roles in media and religious freedom advocacy, Walther also oversaw the Knights’ polling and book publishing operations, which included several New York Times bestsellers. Together with his wife, Maureen, he co-authored “The Knights of Columbus: An Illustrated History,” a book released this year.
