Academic leaders establish 'red lines' as White House pushes universities to conform to its political agenda.

The move follows an increase in tensions on campuses across the country, with universities such as Columbia, Harvard, Yale and Berkeley among those under scrutiny over allegations of anti-Semitism.

Over a dozen faculty members from Princeton University in the US state of New Jersey, joined pro-Gaza hunger strikers in solidarity with Palestine.

Despite mass arrests, starting in Columbia, and the direct violence against peaceful protesters everywhere, the movement has only grown stronger.
