President Obama's advisers were angry with Biden for talking gay marriage

Vice President Joe Biden didn't think he made news when he said he supported gay marriage in 2012

According to a new book about the 2012 US presidential campaign, Vice President Joe Biden was in hot water after he announced he was for gay marriage.

Double Down, written by Mark Halperin and John Heilemann, chronicles the most recent race for the White House.

In the spring of 2012, Biden went  on NBC's Meet the Press and expressed personal support for same-sex marriage.

Halperin and Heilemann, according to Huffington Post, have Obama adviser David Plouffe exploding after Biden's words became public.

'What the fuck? was his [Plouffe's] reaction when he took a look at the transcript. We were going to do this! In the next two weeks! As a fucking surprise! How can this have happened,' the authors write.

The White House plan was to have the president 'evolve' on the topic, mentioning his new stance next time he was asked.

Six days after Biden's Meet the Press appearance, Obama became the first US president to publicly come out for marriage equality.

The vice president did not understand why Obama's team was furious.

'I don't understand why everyone's so mad at me,' the book has Biden saying to a confidant.

However, the former senator from Delaware did apologize to Obama.

Double Down also suggests Obama's "evolve" mantra was political. In 2004, his former press secretary Robert Gibbs heard the then relatively unknown state senator mention he was for marriage rights.
