US: Rubio says he may have revoked 'more than 300' visas over pro-Palestine campus activism 

The latest person to be targeted by federal immigration agents is an Iranian doctoral student

The US State Department may have revoked more than 300 visas, according to Secretary of State Marco Rubio.

Rubio on Thursday said the Trump administration was looking every day for "these lunatics" after federal immigration authorities detained and revoked the visa of a Turkish student.

The announcement is sure to send shockwaves through the international student community.

"It might be more than 300 at this point. We do it every day. Every time I find one of these lunatics, I take away their visas," Rubio said during a press conference in Guyana, as reported by Reuters.

"At some point, I hope we run out because we've gotten rid of all of them, but we're looking every day for these lunatics that are tearing things up."Read more
