ICE arrested anti-Israel protester Mahmoud Khalil without a warrant and says it was legal citing flight risk concerns, new court documents reveal.

On Thursday, Trump administration officials admitted that Columbia student Mahmoud Khalil was arrested without a warrant. Khalil, a green card holder, has been detained since March, when Secretary of State Marco Rubio cancelled his visa over nebulous allegations of "pro-terrorist" speech.

ICE has admitted it detained Mahmoud illegally … to justify it, they are now flat out lying,” said a legal advocate.
