The Trump administration has expanded its immigration crackdown to target legal immigrants and tourists, using aggressive tactics and enhanced vetting at ports of entry. These tactics, which include searching electronic devices and compiling reports on individuals involved in pro-Palestinian protests, have unnerved foreign tourists and immigrant communities. The administration claims that the arrests and detentions are about protecting Americans, but critics argue that the crackdown is an attempt to chill speech and punish individuals for expressing views that the government deems threatening. Free-speech advocates argue that the administration has not produced evidence that the targeted individuals' expressive activities fall outside the protections of the First Amendment.
