Trump shakes up leadership at Homeland Security Department

(AP) – Homeland Security Secretary Kirstjen Nielsen has resigned amid President Donald Trump’s growing frustration and bitterness over the number of Central American families crossing the southern border.

Trump announced on Sunday in a tweet that U.S. Customs and Border Protection Commissioner Kevin McAleenan would be taking over as acting head of the department. McAleenan is a longtime border official who is well-respected by members of Congress and within the administration.

The decision to name a top immigration officer to the post reflects Trump’s priority for the sprawling department founded to combat terrorism following the Sept. 11 attacks.

Though Trump aides were eyeing a staff shake-up at Homeland Security and had already withdrawn the nomination for another key immigration post, the development Sunday was unexpected.
