Via Breitbart:

Barack Obama’s sense of humor fits perfectly with the elitist White House press corps that routinely cover him, and there was never a better example that one remark he made in his series of jokes at the White House Correspondents Dinner Saturday night.

Take note of the journalists’ responses from the transcript. Obama, targeting his intrepid foe Michelle Bachmann, said:

“Of course, even after I’ve done all this, some folks still don’t think I spend enough time with Congress. “Why don’t you get a drink with Mitch McConnell?” they ask.  Really?  (Laughter.)  Why don’t you get a drink with Mitch McConnell?  (Laughter and applause.)  I’m sorry.  I get frustrated sometimes. I am not giving up.  In fact, I’m taking my charm offensive on the road — a Texas barbeque with Ted Cruz, a Kentucky bluegrass concert with Rand Paul, and a book-burning with Michele Bachmann.  (Laughter and applause.)”

A book-burning. He’s essentially calling Bachmann a Nazi or some other kind of fanatic. And note that not only did the audience laugh, they applauded.
