A federal court's ruling Wednesday invalidated thousands of Immigration and Custom Enforcement's immigration detainers sent to more than 30 states, including Texas.

The ruling does not affect those sent to the Travis County Jail, where undocumented immigrants are being held for deportation. But the non-profit group, Grassroots Leadership, expects that to change.

"This court decision essentially confirms what we've been saying for years, which is that not only do immigration detainers in the jail break up immigrant families, but they are also unconstitutional," said Grassroots Leadership Executive Director Bob Libal.

KVUE contacted ICE for a statement. A spokesperson said ICE is reviewing the court ruling to determine its course of action.
