Democratic Senate colleagues are facing criticism after calling for the release of Palestinian activist Mahmoud Khalil, who was arrested by ICE. Republican Senator Tom Cotton condemned the Democrats for supporting a 'pro-Hamas foreigner' who has targeted Jews on campus. The arrest of Khalil, a graduate student and permanent U.S. resident, has sparked a debate about First Amendment rights and the government's authority to revoke visas and green cards. The Trump administration has defended the arrest, claiming that Khalil distributed 'pro-Hamas propaganda' and engaged in 'pro-terrorist, anti-Semitic, anti-American activity.'
