President Donald Trump is going after the oldest United States university in a push to reshape top institutions.  

He's demanding Harvard University makes changes to hiring, admissions, and teaching practices to curb anti-Semitism on campus.   

The institution says no Government should dictate how a private university operates.  

US Correspondent Richard Arnold told Mike Hosking Trump is reacting by freezing close to NZ$3.5 billion in federal funds. 

He says the White House is calling for an end to the tax-exempt status for research operations.
