It’s David Horowitz’s conference.
Yes, he has said plenty of dumb things over decades of political activism, but that conference was always mainstream. Almost every major figure on the right had spoken at it.
The reporters behind this know that. Their own article acknowledges that Rick Perry, Ben Shapiro etc have all spoken there. But they still chose this smear framing.
This is why many on the right view the media as the opposition. Trump takes advantage of it, but they do it to themselves.
Weird. Washington Post somehow skipped that article.
