Homeland Security Secretary Nielsen resigns amid Trump anger over border

Donald Trump, who has recently expressed growing anger about the situation at the border, said on Twitter: "Secretary of Homeland Security Kirstjen Nielsen will be leaving her position, and I would like to thank her for her service."

ted States Homeland Security Secretary Kirstjen Nielsen, who oversaw President Donald Trump's bitterly contested immigration policies during her tumultuous 16-month tenure, resigned on Sunday (April 7) amid a surge in the number of migrants at the border with Mexico.

A senior administration official said Donald Trump asked for Nielsen's resignation and she gave it.
