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,

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

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.
