Des Moines, Iowa (CNN) – Minnesota Rep. Michele Bachmann backed out of a scheduled appearance at a candidate forum sponsored by Veterans for a Strong America in Des Moines on Saturday.
Bachmann skipped the event to prepare for Saturday night's Republican presidential debate in Iowa, said her spokeswoman Alice Stewart. The candidate's husband, Marcus Bachmann, spoke in her stead.
Bachmann was one of four candidates who signed up to speak at the forum. Former House Speaker Newt Gingrich, former Pennsylvania Sen. Rick Santorum, and Texas Gov. Rick Perry each delivered an address, as well.
