Terms of the settlement have not been released, the Minneapolis Star Tribune reported. Lawyers for Barb Heki, who served as home-school coalition director for Bachmann's 2012 presidential campaign, filed a notice Friday of the settlement.
Bachmann, who recently said she would not run for a fifth term in Congress, faces a number of investigations about her presidential campaign.
She announced in June 2011 she was seeking the Republican presidential nomination, came in first in August in the Iowa straw poll and suspended her campaign Jan. 4, 2012, the day after she ran sixth in the Iowa Republican caucuses.
In the lawsuit, Heki said other members of the campaign staff took a mailing list belonging to the Network of Iowa Christian Home Educators from her computer without her consent. The campaign later paid $2,000 to the group for use of the list.
