Columbia University graduate Mahmoud Khalil’s lawyers requested that Secretary of State Marco Rubio testify in Khalil’s deportation case to expand on the Department of Homeland Security‘s evidence submitted Thursday.

DHS lawyers released a two-page memo from Rubio on Tuesday at the request of a judge. The memo outlined the Trump administration’s case for Khalil’s deportation. Khalil’s lawyers argued the memo lacked evidence, and they requested that Rubio testify in court to explain the administration’s decision.
