The Department of Homeland Security has until 5 p.m. Wednesday to provide evidence that Mahmoud Khalil should be deported, or else she'll drop the case Friday, a judge said.

Khalil appeared in a Louisiana courtroom Tuesday, about a month after Immigration and Customs Enforcement agents detained him at his university-owned apartment building in Morningside Heights. He was transferred soon after to a detention facility in Louisiana, where he faces removal proceedings.

A month after Columbia University student Mahmoud Khalil was picked up by immigration agents in New York and transferred 1,200 miles to a detention center in rural Louisiana, an immigration judge on Tuesday gave the government a day to provide evidence he should be deported and said she would rule on that question on Friday.
