The Trump administration and Harvard University on Monday traded barbs in a critical hearing in Boston over the government’s threats to slash billions of dollars in the Ivy League school’s federal research funding.

“Harvard can win in the courtroom but still lose almost everything it’s fought for,” said Allison Wu, the co-founder of the 1636 Forum, a Harvard alumni community named for the year the university was founded, who supports the university’s case.

President Trump took to Truth Social on Monday to criticize the judge presiding over a long-anticipated hearing over his administration’s battle with Harvard University. Harvard is suing the administration over the pause it put on nearly $3 billion of federal research funding,
