According to Republicans in Congress, Vice President Kamala Harris is to blame for this. They have labeled her the Biden administration’s “border czar,” claiming that she has been in charge of immigration-enforcement policies. (They have also made easily disprovable claims that the number of crossings is higher than it actually is.) But Harris is not a border czar—the position doesn’t exist. The people calling her that are doubling down on a misconception that has persisted ever since Donald Trump brought it into the mainstream: that a single person could stop the largest global migration crisis in history, if only the right hard-liner had the job.
