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.

An immigration judge in Louisiana says she will decide whether the U.S. can continue to detain Mahmoud Khalil, the student activist facing deportation.
