Clinton told the concerned crowd that the protestors must be campaigning against Trump because “Trump and his kids have killed a lot of animals.”

The Democratic presidential nominee was referring to a photo of Trump’s eldest sons — Donald Jr. and Eric — hunting big game in Africa several years ago.

It was the first time Clinton has hit at her White House opponent's kin. The rest of the campaign event went off without a hitch and the protesters were removed from the event.
