WASHINGTON (AP) -- Republican presidential candidate Michele Bachmann is acknowledging "misspeaking" occasionally, including wrongly claiming that actor John Wayne was from her Waterloo, Iowa hometown, but says she's "a substantive, serious person" who would be a good president.

Announcing her candidacy on Monday, Bachman flubbed her hometown history in declaring "John Wayne was from Waterloo" and "that's the kind of spirit that I have, too."

The actor was born nearly 150 miles away. It was the serial killer John Wayne Gacy Jr. who lived, for a time, in Waterloo.

Bachmann said her comments "were just misspeaking."

"I wish I could be perfect," Bachmann told CNN on Tuesday. "I'm a substantive, serious person" who has "good sense on how to turn the economy around" as president.
