NEW YORK (AP) - Fox News Channel's Chris Wallace says that he "messed up" by asking Republican presidential contender Michele Bachmann whether she's a flake.

The talk show host posted the video apology after his "Fox News Sunday" interview with the Minnesota congresswoman, who formally announced her presidential bid Monday in Iowa. Wallace said on the Fox show that Bachmann had a reputation in Washington for making questionable statements and asked her: "Are you a flake?"

Bachmann said she's a "serious person" and found insinuations that she was a flake to be "insulting."

Wallace said later that since "it's really all about the answers and not the questions, I messed up. I'm sorry. I didn't mean any disrespect."
