Well ... I’m sorry to say I have no idea what you’re talking about ... :-) ...
Are you thinking of David Horowitz? This guys not him. At least he doesn’t look like him in the picture.
I believe you’re getting David Horovitz mixed up with David Horowitz.
Here you go:
David Horovitz(born 12 August 1962) is a British-born Israeli journalist, author and speaker. He is the founding editor of The Times of Israel, a current affairs website based in Jerusalem that launched in February 2012. Previously, he had been the editor-in-chief of The Jerusalem Post.

David Joel Horowitz (born January 10, 1939) is an American conservative writer. He is a founder and current president of the think tank the David Horowitz Freedom Center, editor of FrontPage Magazine, and director of Discover the Networks, a website that tracks individuals and groups on the political left. Horowitz founded the organization Students for Academic Freedom, whose self-stated goal is combating what it calls the “leftist indoctrination” in academia.
