Acting Homeland Security Secretary Kevin McAleenan is resigning from his post after six months, President Trump confirmed Friday. Trump tweeted that he and McAleenan "worked well together" and that the secretary helped decrease the number of crossings at the southern U.S. border, but he now wanted "to spend more time with his family and go to the private sector." However, reports indicate that McAleenan was privately at odds with the Trump administration's immigration policies, which led to frustrations within the White House. During his tenure, McAleenan expanded a program that has forced around 50,000 migrants to remain in Mexico and signed deals with Guatamala, El Salvador, and Honduras that would deny asylum protections in the U.S. to migrants if they failed to apply for asylum in another country during their journey.
