Minnesota Rep. Michele Bachmann on Thursday became the first presidential candidate to sign an anti-gay marriage pledge, the Des Moines Register reported.

The pledge, announced Thursday by the Iowa-based Christian conservative group The Family Leader, asks 2012 candidates to “vigorously” oppose marriage equality, be faithful to their own spouse, vow to protect women and children from pornography and reject Sharia law because it is a “form of totalitarian control.”
The pledge ironically also asks candidates to have “Respect for the marital bonds of others.”
A footnote in the document suggests being gay is a choice.

Bachmann, who in 2004 as a Minnesota senator sponsored a constitutional amendment to ban gay marriage in the state, signed the pledge on Thursday. An aide of the candidate, Alice Stewart, told the paper that Bachmann had no qualms about signing the pledge.

“She has been married for over 30 years and has a strong marriage and faith,” Stewart said.
A spokesman for former Minnesota Governor Tim Pawlenty said he is reviewing the document.
The White House offered no comment.
