I've never heard of him, but just reading the short bio at the end of this strongly suggests he's not exactly an objective observer either:
> Jonathan Turley is the Shapiro professor of public interest law at George Washington University and the author of “The Indispensable Right: Free Speech in an Age of Rage.”
The bio left out the part mentioning he's a regular Fox News contributor.
He also was a regular MSNBC contributor, what is your point?
