Attorneys for Alma Centeno Santiago, an undocumented pregnant woman detained in Queens this year, were able to halt her deportation last week with an unusual argument for such a case—that the federal government was violating her free speech rights under the First Amendment.

They'll now make the same argument, among others, in federal court Tuesday in an effort to keep Santiago in the country and have her released from federal detention.

The outcome of the case could have broader implications for conditions at federal immigrant detention centers and the due process rights of undocumented immigrants. Santiago has claimed that, while in federal custody, she's been denied medical care and basic necessities.
