The U.S. General Services Administration asked federal agencies to reconsider all federal contracts with Harvard.

Harvard University asked a federal judge on Monday to issue a summary judgment ruling to unfreeze $2.5 billion in funding blocked by President Donald Trump's administration, which Harvard said was illegal.

Other schools face the loss of federal funding and their ability to enroll international students if they don't agree to the Trump administration's shifting demands. But Harvard, which was founded in 1636, a century and a half before the nation itself, is taking the lead on defying the White House in federal court — and paying a significant price.
