DHS Secretary Kirstjen Nielsen Is Out. Here's Who's Taking Her Place (For Now).

Department of Homeland Security Secretary Kirstjen Nielsen is officially leaving her post, according to a series of tweets made by President Donald Trump on Sunday evening. 

U.S. Customs and Border Protection Commissioner Kevin McAleenan will become Acting Secretary once Nielsen vacates the position.

According to CBS News, Nielsen had a 5 p.m. meeting with President Trump. 

Nielsen was allegedly scheduled to talk to the president about immigration and border issues. She had no intention of resigning but personnel changes are being pushed for in the Trump administration, CNN reported.

From CNN:

The source notes Trump's frustration with the current asylum laws, and his desire for individuals who work for the administration to just stop central American asylum seekers from entering the United States, contrary to the law.

Separately, a source close to Nielsen and an administration official said she was blindsided by the White House pulling Ron Vitiello's nomination to be director of Immigration and Customs Enforcement and has heard of other impending immigration-related personnel changes, so she asked for a meeting with Trump to get a sense of his thinking.

According to the Washington Examinerthe White House called Vitiello on Thursday night to let him know his nomination had been rescinded, meaning he wouldn't travel with Nielsen and Trump to the border on Friday. 

It has been rumored that Vitiello's nomination was pulled because he was not endorsed by ICE union leader Chris Crane.
