From FrontPage Magazine, I found the following article: "Penn. Legislature Joins the Fight Against Intolerance." These last two paragraphs are precious:
Much of the Pennsylvania bill was borrowed from the Horowitz group's "academic bill of rights."
Rep. Mark Cohen, D-Philadelphia, referred to the Horowitz group and said the resolution is just "an attempt to respond to a national movement. ... We're just trying to fall in line."
