WASHINGTON (FOX 5 DC) - Department of Homeland Security Secretary Kirstjen Nielsen has resigned after a meeting with President Trump Sunday evening.
President Donald Trump tweeted the news shortly after 6 p.m.
The President noted that U.S. Customs and Border Protection Commissioner Kevin McAleenan will become acting secretary in her place.
Sunday's meeting took place amid an ongoing influx of migrants at the U.S.-Mexico border that has been taxing America's immigration system and sparking frustration within the White House.
On Friday, Trump confirmed he withdrew the nomination of acting Immigration and Customs Enforcement (ICE) Director Ron Vitiello to become the permanent head of the agency, telling reporters that "Ron's a good man, but we're going in a tougher direction, we want to go in a tougher direction."
