Nothing wrong with being a 'flake,' says Rep. Flake

It's not easy being a 'flake' this week.

Rep. Jeff Flake (R-Ariz.) questioned the offense of the word on Twitter Monday.

"'Is there something wrong with that?" he questioned.

The word "flake" made headlines this week following an interview in which Rep. Michele Bachmann (R-Minn.), who announced her candidacy for president Monday morning, defended herself from the characterization.

On Sunday, Fox News's Chris Wallace asked Bachmann, "Are you a flake?" Bachmann later refused to accept Wallace's public apology, saying it was "insulting to insinuate that a candidate for president is less than serious."
