Washington — The Trump administration said Monday it would cut off all new federal research grants to Harvard University in the latest escalation of its battle with the school.

The CEOs of NPR and PBS said on Sunday's "Face the Nation" they will challenge Trump's executive order to end federal funding to the organizations.

In an unprecedented move, the CEO of PBS has sounded the alarm over a new executive order that threatens to cut crucial federal funding. 'We've never seen anything like this,' she warns, hinting at the potential impact on public media across the nation.
