Found this interesting. The LA times posted this letter from 2007 that was sent to them from Trump who was threatening to sue them for a story they did on Trump university. What I find interesting is look at the similarities between things he said then, and things he says now. It's obviously not an act. Also I like how even in the letter he lies about never having been bankrupt.
Maybe it's not like he claims that the media is against him, perhaps he's always just been a pompous jerk to the press as evidenced by this letter.
