One of Bachmann's top supporters in Iowa caused a stir on Twitter when he led followers to believe Herman Cain's campaign was emptying out its Iowa headquarters.

Kent Sorenson, Bachmann's Iowa chairman, sent out a tweet on Tuesday claiming that moving trucks were parked outside Cain's Iowa office.

He included a photo of the trucks â€" which Cain's campaign later said were actually there to deliver materials for the campaign, including boxes of yard signs.

The tweet has since been deleted.

Bachmann's Iowa campaign manager, Eric Woolson, later apologized, telling CNN it was his fault and an unnecessary distraction.

The continuation of Cain's presidential campaign has remained an open question all week after he told supporters on a conference call Tuesday that he was reassessing his candidacy. Cain said Wednesday that he is consulting with his wife and will make a decision within a week.
