Democratic Sen. Elizabeth Warren (Mass.) continues to receive hefty donations from individuals from the securities and investment industry, records show.

Warren, who has positioned herself as a fighter against Wall Street and corporate interests, has amassed $660,000 in campaign contributions from the securities and investment industry, making the sector the sixth most generous to her campaign committees since first running for Congress in 2011.

Warren has also received $2.4 million in donations from lawyers and law firms, the second most of any industry that has given to her campaigns.

Firms represented on the list of biggest donors deal with issues such as bankruptcy, white-collar crime, and corporate restructuring.

Warren has taken thousands more since last year from employees at Brown Rudnick LLP, an international firm that focuses on high-stakes litigation.

Brown Rudnick claims "deep experience with specialized industries including technology, health care, energy, government services, venture capital and hedge funds."

Individuals at Brown Rudnick have now contributed a total of $72,477 to Warren's campaigns. An additional $1,000 has been given from the firm's political action committee. Individuals from Brown Rudnick have been the eighth most generous to Warren.

Ropes & Gray LLP, a global law firm that represents clients on internal investigations and government enforcement matters, defends white-collar criminals. The firm additionally represents clients on matters dealing with Medicare and Medicaid fraud, financial crimes, and public corruption and campaign finance enforcement issues.

Ropes & Gray employees have given $57,725 to Warren's campaigns, enough to make them the senator's tenth largest contributor.

Mintz Levin, a Boston-based law firm, focuses on bankruptcy and corporate securities. Employees at the firm have contributed $48,550 to the senator.

People who work at Goodwin Procter LLP, which also deals with financial institutions and white-collar defense, have added $35,115.

Before joining the Senate in 2012, Warren was the Leo Gottlieb professor of law at Harvard Law School, a position that paid her $350,000 per year.

The position was endowed by the Cleary Gottlieb law firm, which helped "multinational banks that profited from the Bernie Madoff fraud avoid paying compensation to Madoff victims," National Review previously reported.

Warren's office did not return requests for comment on the donations.
