A group of Harvard University alumni urged the school not to cave to the Trump administration’s demands as it restarts talks with the White House.President Donald Trump on Friday said his administration had been holding talks with Harvard and may announce a “‘mindbogglingly’ HISTORIC” deal over the next week.

The Trump administration has frozen nearly $3 billion in federal grants and contracts with Harvard University and said the school is no longer eligible to receive new grants. Trump is also going after the institution’s eligibility to enroll international students, who contributed $383.6 million to the state’s economy last academic year.

More than 900 research grants worth $2.6 billion are in jeopardy. So is the 80-year-old model of American science.
