Several GOP presidential candidates vow to punish colleges, students protesting against Israel or for Hamas

Several Republican presidential candidates say they'd punish university students who demonstrate against Israel or in support of Hamas, the militant group governing Palestinians on the Gaza strip. Hamas has been designated as a terrorist organization by the U.S.

Multiple GOP candidates say they'd take punitive action, including canceling visas for international students who demonstrate in support of Hamas, or even more broadly, "anti-American and antisemitic foreigners at our colleges."

But the candidates have not offered details about how or whether they would distinguish international students who express support for the Palestinian people from those they claim have links to Hamas. Nor have they said what mechanism would be used to revoke student visas.
