Elizabeth Warren, the Senate candidate from Massachusetts who's running on her history as an advocate for middle class consumers, earned more than $700,000 total in consulting fees, book royalties and a law professor salary from 2010 to 2011.

According to her personal financial disclosure report submitted to the U.S. Senate's Office of Public Records, Warren earned a $429,981 salary as a professor at Harvard Law from 2010-2011. The report also shows that Warren earned an additional $136,946 in royalties for books she wrote, along with $133,938 in consulting fees.

Warren, whose campaign recently  raised $5.7 million in the fourth quarter of 2011, is hoping to unseat Senator Scott Brown this fall. Warren has been positioning herself as an enemy of big banks and a strong advocate for the middle class. She's even been quoted as saying that she "created much of the intellectual foundation" for the Occupy Wall Street movement.

The race has already received a great deal of attention, with conservative groups such as Crossroads GPS, backed by Karl Rove, already running ads against Warren in Massachusetts. Today the U.S. Chamber of Commerce, a powerful lobbying organization that represents many American businesses, announced their intentions to be "significantly involved" in the race.

Senator Brown's campaign, along with the conservative groups targeting Warren, will almost surely use the numbers from this disclosure report against her throughout the course of what is shaping up to be a tight race.

A financial disclosure report from summer of 2011 showed that Brown received a $700,000 advance for his book "Against All Odds," a personal memoir released in February, 2011, which made The New York Times bestseller list.

ABC News emailed Warren's campaign for comment, and they did not respond.
