Obama told ABC's "Good Morning America" that he was planning to announce his support for gay marriage sometime before the Democratic convention in September, but that things changed when Biden unexpectedly said Sunday that he is "absolutely comfortable" with same-sex marriage.
"He probably got out a little bit over his skis," Obama said, "but out of generosity of spirit."
"I had already made a decision that we were going to probably take this position before the election, before the convention," he said.
Asked if he was upset with Biden for his comments, the president said he was not.
"Would I have preferred to have done this in my own way, in my own terms, without, I think, there being a lot of notice of everybody? Of course," he said. "But all's well that ends well."
Below, reactions to Obama's announcement from around the political world:
