The Obama 2012 campaign on Friday released footage of Elizabeth Warren's interview for "The Road We've Traveled," the upcoming documentary about the Obama presidency.

"Why didn't someone wave a magic wand and make it all better?" she said. "Because that's not how the world works. It took a long time to shake the foundations of America's middle class. But it also means it's also going to take some time to put it back together."

Without mentioning names, Warren also took a shot at Obama's Republican rivals.

"This next election is about the direction that our country takes, it's about whether or not we are going to be a people that say, 'I got mine, the rest of you are on your own'," she said. "What our future looks like is going to be very different depending on who's governing."

Warren, who is currently running for U.S. Senate in Massachusetts, is an outspoken advocate for financial reform and a strong critic of the financial institutions involved in the 2008 economic crash. A founding figure of the Consumer Protection Finance Bureau, she once said that Wall Street "broke this country."

Though Warren appears in the film, she isn't always so supportive of the president. Last week, she told the Washington Blade that Obama "needs to evolve" on same sex marriage.
