Mohsen Mahdawi, a 34-year-old U.S. permanent resident who was raised in a refugee camp in the West Bank, was detained during his April 14 naturalization interview in Vermont.

The legal basis for the challenge by the Trump administration to US District Court Judge Geoffrey Crawford’s decision was not immediately available Thursday morning.

Columbia University student Mohsen Mahdawi left federal prison, but his case isn't over. His lawyer says the Trump administration's case against him is "laughable" and "unconstitutional."
