Bill White, an openly gay supporter of Mitt Romney, has decided to withdraw his support for Romney and back President Barack Obama instead. White had given $2,500 to the Romney campaign.
White is the chairman and CEO of the New York-based consulting firm Constellations Group. White told CNN he has advocated on behalf of injured and fallen veterans for 20 years, and has been awarded the Meritorious Public Service Award from the Coast Guard and from the Navy
In a letter obtained by CNN, White wrote: "I feel that I no longer wish to support your presidential campaign and ask that you please return the maximum contribution that I gave to you last year. You have chosen to be on the wrong side of history and I do not support your run for president any longer."
"Several days later this past Saturday to a packed stadium of young college students you made the following statement that 'Marriage is only between one man and one woman,'"
"I believe that you will do as you now say and try to force a constitutional amendment which would attempt to make my own legal and blessed marriage null and void."
In an interview with CNN, White said: "Quite frankly, I was not supporting Barack Obama, I was supporting Mitt Romney. And my support is not just words or my vote, it's also putting my money where my mouth is."
"I'm looking at a guy who I'm supporting for president, and who I want to be my president and who I've given my money to, to be president, saying something I didn't think he would be saying."
"Now, I feel like he's declared war on my marriage. And I could just sit back and not say anything. Or I could do something about it. And I've chosen to do something about it."
CNN contacted the Romney campaign, but did not receive a response.
