The state of Texas is suing the United States government, the Associated Press reports, in an effort to stop 6 Syrian refugees from being resettled in Dallas this week. Governor Greg Abbott has consistently sought to impede the arrival of refugees in his state since the terror attacks in Paris last month.

The lawsuit was filed in federal court in Dallas on Wednesday by Texas Attorney General Ken Paxton on behalf of the state’s Health and Human Services Commission. According to the Dallas Morning News, it names the U.S. State Department and the U.S. Health and Human Services Department, as well as the International Rescue Committee, a New York-based aid agency.

The IRC, a federal resettlement contractor, confirmed earlier on Wednesday two Syrian refugee families were scheduled to arrive in Dallas on Friday. The lawsuit, citing “reasonable concerns about the safety and security of the citizenry of the State of Texas,” seeks to block their arrival.

From the News:

Citing potential for “irreparable harm,” the state reiterated in the law suit many of the security concerns that it has previously outlined. And it said that the IRC refused to comply with federal law to “consult with the State in advance on placement of refugees in Texas.”

“Whatever ‘advance consultation’ and ‘close cooperation’ mean, this is not it,” said the lawsuit, which names the U.S. State Department and the U.S. Health and Human Services Department.

“We have been working diligently with the International Rescue Committee to find a solution that ensures the safety and security for all Texans, but we have reached an impasse and will now let the courts decide,” Bryan Black, a spokesman for HHSC, said.
