(CNN) - Hours after endorsing same-sex marriage in an interview with ABC News Wednesday, President Barack Obama sent an explanation of the decision to supporters, ending with a request to donate to his re-election campaign.
"Today, I was asked a direct question and gave a direct answer: I believe that same-sex couples should be allowed to marry," Obama wrote in the email.

He went on: "I respect the beliefs of others, and the right of religious institutions to act in accordance with their own doctrines. But I believe that in the eyes of the law, all Americans should be treated equally. And where states enact same-sex marriage, no federal act should invalidate them."
The last line was a call for donations: "More than 1.9 million people like you power this campaign. If you can, please donate today," Obama wrote while linking to a form for giving money to his campaign.
