Completely untrue that she was tasked to be border czar.
The phrase “border czar” isn’t an official title, but still carries connotations of authority. In politics, “czar” typically refers to a government official tasked with managing a major issue, according to the Cambridge Dictionary.
In Harris’ case, the label comes from President Joe Biden’s March 2021 decision to assign her the duty of addressing the “root causes” of migration from Honduras, Guatemala, and El Salvador. She was also tasked with encouraging leaders in those countries, as well as Mexico, to enforce immigration laws.
Harris was never asked to be the “border czar,” however, and she was never specifically given the responsibility for security on the border. Harris was also not empowered to set U.S. immigration policy — only the president can sign executive orders and Harris was not empowered as Biden’s proxy in negotiations with Congress on immigration law.
