Reuters reports that Homeland Security Secretary Kirstjen Nielsen will be stepping down.

“Her departure was first reported by CBS News, which said it was unclear whether Nielsen’s departure would be voluntary.”

Reportedly, Kevin McAleenan, the current U.S. Customs and Border Protection commissioner, will be acting DHS secretary.
