Bachmann adviser says Minnesota congresswoman to end bid for GOP presidential nomination

DES MOINES, Iowa - An adviser to Michele Bachmann says the Minnesota congresswoman is ending her bid to win the Republican presidential nomination after coming in last in the Iowa caucuses.

Bachmann finished sixth out of six candidates in the first of many contests to pick a Republican presidential candidate.

She cancelled appearances planned for Wednesday in South Carolina and scheduled a news conference in Des Moines, Iowa, instead.

The adviser requested anonymity to speak before Bachmann makes the announcement.
