Rush Limbaugh, Sean Hannity, Michael Savage, Mark Levin, Laura Ingraham, Mark Steyn and others have referenced FR over the years; many of them are members or lurkers. All use FR as a source.
The demise of Dan Rather and the Dipsy Twits Dixie Chicks are even better examples of direct reporting with real consequences.
I have heard that people close to Trump frequent FR.
If they don’t...they should! (But I believe they do)
