From CNN:
Bachmann, a Minnesota congresswoman, and her husband Marcus withdrew their membership from Salem Lutheran Church in Stillwater, Minnesota last month, according to church officials.
The Bachmanns had been members of the church for more than 10 years, according to Joel Hochmuth, director of communications for the Wisconsin Evangelical Lutheran Synod, the broader denominational body of which Bachmann’s former church is a member.
The church council granted the Bachmanns’ request to be released from their membership on June 21st, Hochmuth said.
After declaring at the CNN/WMUR/New Hampshire Union Leader presidential debate that she would seek the nomination, Bachmann formally announced her presidential bid June 27th in Waterloo, Iowa.
