The letter, dated June 19 and released late June 20, was signed by Cardinal Daniel N. DiNardo of Galveston-Houston, USCCB president; Bishop Oscar Cantu of Las Cruces, New Mexico, chairman of the USCCB Committee on International Justice and Peace; and Bishop Joe S. Vasquez of Austin, Texas, chairman of the USCCB Committee on Migration.

"With the exception of two individuals, all those arrested remain in ICE custody," Khaalid Walls, northeast regional communications director for ICE, told Catholic News Service in an email.

Regarding the ICE action June 11, Walls confirmed that officers arrested 114 Iraqi nationals in Detroit. In the rest of the country, 85 others have been arrested in ICE's recent enforcement efforts.

"As a result of recent negotiations between the U.S. and Iraq, Iraq has recently agreed to accept a number of Iraqi nationals subject to orders of removal," Walls said to CNS in an email. "As part of U.S. Immigration and Customs Enforcement (ICE) efforts to process the backlog of these individuals, since May 2017, the agency has arrested 199 Iraqi nationals nationwide, the overwhelming majority of whom had criminal convictions for crimes including homicide, rape, aggravated assault, kidnapping, burglary, drug trafficking, robbery, sex assault, weapons violations and other offenses."

WJBK-TV in Detroit reported that an ICE spokesperson said that "each of these individuals received full and fair immigration proceedings, after which a federal immigration judge found them ineligible for any form of relief under U.S. law and ordered them removed."

Cardinal DiNardo and Bishops Cantu and Vasquez acknowledged that some of those apprehended may have orders of deportation because they have committed criminal offenses in the past, but they still expressed grave concern they would then be sent back to a country where religious persecution and persecution against ethnic minorities remains an ongoing threat.

"We do not minimize the serious criminal offenses of which some of these individuals have been convicted; it is entirely appropriate that they be punished for their offenses. After serving their sentences, however, we believe it would not be just or humane to deport a person who has integrated into American life and poses no evident risk to the local community," the bishops said.

"The fact that they have a significant risk in experiencing persecution, and even possible bodily harm because of their faith is, from our moral perspective, an important factor to be weighed in the calculation to deport," they said.

"For decades, many of these Christians sought legal refuge in the United States. Like other refugees from various countries of origins, they have become integrated into American communities, and in this instance, they are contributing members of communities in Michigan and Tennessee," they wrote.

The American Civil Liberties Union filed a class-action lawsuit against ICE June 15. The complaint was filed by seven individuals on behalf of themselves and all those similarly situated.

"U.S. law prohibits the removal of individuals to countries where they would face a likelihood of persecution or torture," petitioners wrote in the complaint. "For example, many of the petitioners are Chaldean Christians, who are widely recognized as targets of brutal persecution in Iraq."
