Thousands of University of California and California State University system workers are unsure about their jobs and the future of their research after reports that President Donald Trump is going after the federal funding for California.

The Trump administration is preparing to cancel a large swath of federal funding to California, an effort which could begin as soon as Friday, according to multiple sources.

California officials on Friday braced for what they believe is a significant escalation in President Donald Trump‘s efforts to squeeze the state financially, possibly cutting off all federal funding to the University of California and the California State University systems.
