The CEO of a Raleigh marketing firm is apologizing for an ad posted on Twitter that depicted an ISIS execution – and a burger.

Valor Media created the campaign for a Washington, D.C., chain called Z-Burger.

Over the weekend, a tweet was sent out that showed a photo of American journalist James Foley moments before he was executed by ISIS in 2014 – along with the image of a hamburger.

Z-Burger had the tweet removed within an hour. Michael Valor, whose business created the tweet, says he takes full responsibility and posted a video on Twitter apologizing.

Valor also said that his company will be helping to raise money for the Foley Fund.
