The acting head of the U.S. Department of Homeland Security on Wednesday announced a probe into the 'disturbing and inexcusable' posts allegedly made by border patrol agents in a secret Facebook group.
The posts - uncovered by Propublica - included jokes about the deaths of migrants and sexually explicit content referring to Congresswoman Alexandria Ocasio-Cortez.
In a Tweet, Secretary Kevin McAleenan said the posts were 'unacceptable' and that those found responsible 'will be held accountable.'
The move comes amid mounting criticism over the Trump administration's handling of a humanitarian crisis on the border… with lawmakers and government watchdogs sounding the alarm.
