1. A purge at the Department of Homeland Security.

A day after pushing out the secretary, Kirstjen Nielsen, President Trump moved to sweep out others in the department’s top ranks: the head of U.S. Citizenship and Immigration Services, the Secret Service director and the department’s general counsel.

Mr. Trump has been pushing for even harsher border policies than Ms. Nielsen presided over, and to resume separating families. Above, Central American migrants turned themselves in at the border in Texas on Saturday.

And his scrutiny of the Secret Service appears to have risen since agents arrested a Chinese woman over a week ago at Mar-a-Lago, his Florida resort. More details about that case came out at a court hearing today.
