I have not found the real press release yet, but
Senator Heitkamp supports gay marriage
And if this is part of the statement: I have concluded the federal govt should no longer discriminate against people who want" same sex marriages
Donnelly: Sen. Joe Donnelly: "I have concluded that the right thing to do is to support marriage equality for all.”
Its not exactly a ringing endorsement, but its good nonetheless.
I will add more as I find them, I am just getting the info at the moment off of Sam Stein's Twitter feed.
Update: Here is the Huffington Post story: Heidi Heitkamp, Joe Donnelly Back Gay Marriage
Heidi's statment:
"In speaking with North Dakotans from every corner of our great state, and much personal reflection, I have concluded the federal government should no longer discriminate against people who want to make lifelong, loving commitments to each other or interfere in personal, private, and intimate relationships," said Heitkamp in a statement. "I view the ability of anyone to marry as a logical extension of this belief. The makeup of families is changing, but the importance of family is enduring."
Donnelly's:
"In recent years, our country has been involved in an important discussion on the issue of marriage equality," Donnelly said on Facebook. "While serving in the House of Representatives, I had the opportunity to act on a core belief of mine: we are a stronger country when we draw on the strengths of all Americans. I voted to repeal ‘don't ask, don't tell’ and was an original supporter of the bill that would make it illegal to discriminate against someone in the workplace because of their sexual orientation. It is also for that reason that I oppose amending either Indiana’s or our nation’s constitution to enshrine in those documents an ‘us’ and a ‘them,’ instead of a ‘we.’ With the recent Supreme Court arguments and accompanying public discussion of same-sex marriage, I have been thinking about my past positions and votes. In doing so, I have concluded that the right thing to do is to support marriage equality for all."
