If he really wants to go after them he’d find some way to impair federal research funding. That’s what keeps lights on at MIT. Lincoln labs can be left alone for now but the rest of it... get Congress to pass some anti-DEI language for the award of grants.
Since DEI specifically violates federal civil rights laws, the federal government can turn the screws a lot tighter than that. They can not only cut off research grants, they can rule a university off limits for students’ federal financial aid.
