Two former staffers of Minnesota Rep. Michele Bachmann have joined the coalition to approve a proposed constitutional amendment which would define marriage as a heterosexual union.

According to, Andy Parrish, who worked as chief of staff on Bachmann's presidential campaign, has joined Minnesota for Marriage, the coalition of groups working to pass the gay marriage ban.

“Looking forward to starting my job today!” Parrish tweeted to his more than 700 followers last month. “I will be working on passing the marriage amendment here in Minnesota. Will miss being at home with my wife and kids!”

The group confirmed the hire on Facebook.

“We are pleased to announce that long time Minnesota political veteran Andy Parrish has joined our team at Minnesota for Marriage as our Deputy Campaign Manager! Welcome aboard Andy!”

Additionally, reported that Tim Gould serves as the group's grassroots director. Gould worked on Bachmann's campaign as its constituent services officer.

During her tenure in the Minnesota Senate, Bachmann served as chief sponsor of the marriage amendment and has endorsed the current effort.
