Brietbart is the owner of the "Big Government" site which was launched only just today. NOT the NY Post guy you're flagging.
Breitbart runs news "portals", similar to the "Drudge Report". In other words, aside from writing a paparazzi column entitled "BigHollywood", for the Washington Times (talk about questionable), his only contribution is that he has a couple of websites that link other people's opinions and stories.
But the site has Micheal Flynn listed as the Editor in Chief.
And, looking into it further, I actually now notice that he didn't even work for the "Post", he has just been "cited" by them. LOL.
