I wouldn't be surprised if trump has in some way violated statute in relation to freedom of speech or academic independence but unless somebody makes a compelling argument that he has, he is a representative of the people operating under the authority granted to him as president, and being a wreckless fool doesn't change that.
I don't particularly like what he's been doing in his second term so far but in online discourse I've seen this worrying trend recently where people think that unelected bureaucrats who were hired because other unelected bureaucrats liked their resumes should be able to hamstring the president and overrule him (i think the strangest thing i've seen was people opining that the CIA should be getting involved). I think it's important to remember that the checks and balances in the US constitution are between the three branches of the federal government, and most of the big bureaus/departments/etc are under the executive branch which he is the sole executive of for the next four years.
