DES MOINES, Iowa (AP) - Minnesota Congresswoman Michele Bachmann is returning to Iowa to headline a Republican Party event in Des Moines this month, as she nears a decision whether to run for president.

Bachmann is weighing a campaign for the 2012 GOP presidential nomination. She says she plans to announce whether she'll run by June.

Bachmann has begun lining up supporters and potential campaign staff in Iowa. Iowa is expected to host the leadoff presidential nominating caucuses in February.

She is scheduled to speak at the Polk County Republican Party's annual dinner on May 26, and plans to speak at a GOP event in Scott County on May 27, aides said.

It would be the fourth visit of the year to Iowa this year by the three-term US House member from a Minneapolis suburb.
