The number of people arrested crossing the border illegally dropped 44% in February, Trump's first month in office. That's a drop from 42,500 arrests in January to 23,500 arrests in February, according to the Associated Press.
Department of Homeland Security Secretary John Kelly called it an "encouraging" trend since fewer families are putting themselves at risk. Kelly credited Trump for the decline and added smugglers are charging much more for border crossers, causing demand to taper off.
