Hundreds of demonstrators marched downtown while a spokeswoman for President Trump said the president had the authority to detain Mahmoud Khalil.

The Trump administration said it is using intelligence collected by the Department of Homeland Security to identify international students who participated in protests against the Israel-Hamas war across dozens of college campuses last year,

White House Press Secretary Karoline Leavitt alleged that Khalil had played a role in organizing demonstrations at which fliers were handed out bearing a logo for Hamas, which she did not display.
