FIRST ON FOX: Former President Trump condemned the violent anti-Israel protests erupting on college campuses overnight, telling Fox News Digital that "weak and ineffective leadership" at universities must be immediately "replaced," while declaring that antisemitism "must be stopped quickly and effectively.

The former president and presumptive Republican presidential nominee was reacting to chaos on college campuses across the nation—from UCLA to Tulane University to Columbia University to the University of Arizona and beyond. 

Pro-Palestinian agitators clashed with pro-Israel students on UCLA’s campus overnight, with local officials warning students that the campus was "out of control" and "no longer safe." 

Police with riot gear arrived at UCLA shortly after 1:00 a.m. at UCLA to gain control of campus amid hours of violence between anti-Israel and pro-Israel counterprotesters.
