U.S. Department of Homeland Security officials knew in 2016 about a private Facebook group where border agents posted racist and misogynistic comments, acting DHS Secretary Kevin McAleenan said on Sunday. The Customs and Border Protection (CBP) service came under fire over the issue last Monday, when the nonprofit news site ProPublica reported that offensive content had been posted on a private Facebook group for current and former CPB officers. McAleenan said the Facebook page was a private site run by a group of individuals in their off-duty hours and not under CBP control.
