Book: White House Caught Off Guard by Biden's Gay Marriage Support

According to author Jo Becker, whose Forcing the Spring hits bookstores next week, the administration's assertions that Biden was sent as a trial balloon were not accurate and some aides wanted President Obama to come down hard on Biden, which he didn't. Forcing the Spring details the strides the LGBT community has made in getting same-sex marriage legalized over the past few years.

Biden, who was speaking entirely off the cuff, basically forced the president's hand. In a tweet after Meet the Press, Obama senior adviser David Axelrod wrote, "What VP said-that all married couples should have exactly the same legal rights-is precisely POTUS’s position."

Since it was an election year, Obama was apparently agonizing about when to show his support for same-sex marriage. However, on May 10, 2012, he did just that in an interview with ABC News’ Robin Roberts.

The president described his thought process as an “evolution” that led him to this place, based on conversations with his own staff members, openly gay and lesbian service members, and conversations with his wife and own daughters.

In 2004, as a candidate for the U.S. Senate, Obama cited his own religion in framing his views: “I'm a Christian. I do believe that tradition and my religious beliefs say that marriage is something sanctified between a man and a woman."
