Border czar Tom Homan said even though President Donald Trump has only been back in office since Monday afternoon, the situation at the U.S.-Mexico border has changed dramatically.

Within hours of entering office, Trump signed several executive orders regarding immigration, including declaring a national emergency over the matter. Additionally, Trump ended the catch-and-release practice, birthright citizenship, and the CBP One app. In the meantime, he suspended foreign aid and refugee resettlements.
