The Trump administration is testing a secretive, never-before-used deportation court for alleged alien terrorists with a case concerning the Afghan mother of a convicted terrorist, with the Justice Department accusing the Texas-based woman of having ISIS sympathies.

The Alien Terrorist Removal Court will have its first ever hearing Thursday at 11 a.m.ET, court documents made public Wednesday night revealed. The Justice Department is asking the court — which has lain dormant since it was created 30 years ago — to deport Nazira Haji Zada, whose son was convicted last year for an ISIS-aligned terrorist plot targeting the 2024 Election, according to the filings.

Zada herself has no criminal history, the court filings said. But DOJ described her in an unclassified summary of the case as having “worked to indoctrinate her children with ISIS ideology and have them pledge loyalty to ISIS.”

“The underlying information is classified because disclosure would enable terrorists and terrorist organizations to avoid preventative or detection measures or would reveal FBI or other U.S. Intelligence Community sources and methods by which such information is obtained,” the DOJ said in the unclassified summary.
