The Times has more on the purge (which they call a purge right up front):

President Trump moved to sweep out the top ranks of the Department of Homeland Security on Monday, a day after pushing out its secretary, Kirstjen Nielsen, accelerating a purge of the nation’s immigration and security leadership.

Government officials said three more top department leaders were expected to leave soon: L. Francis Cissna, the head of U.S. Citizenship and Immigration Services; Randolph D. Alles, the Secret Service director; and John Mitnik, the agency’s general counsel.

…

All were viewed as allies of John F. Kelly, the president’s former chief of staff and his first Homeland Security secretary, who left late last year after months of tension with Mr. Trump.

In other words they were horrible, as Kelly was horrible, but they weren’t horrible enough. Horrible enough is an elusive prize for Trump.

The departures appeared to be part of a housecleaning of officials involved in the Trump administration’s immigration agenda as the president demands a harder line on border security. Mr. Trump on Friday said Mr. Vitiello would be replaced with someone who would move ICE in a “tougher” direction. All of the departing officials were appointed by Mr. Trump.

More grabbing children away from their parents, never to see them again; more talk of “shithole countries” and “not people, animals.”

We’re in a bad place.
