Elizabeth Warren, only minutes before tonight’s second high-stakes face off with U.S. Sen. Scott Brown in Lowell’s Tsongas Center, released a list of her corporate clients in a last-ditch effort to blunt criticisms that the consumer advocate has profited from big corporations while she claims to fight for the little guy.

Warren’s list of clients includes AARP, where her campaign said she fought to protect retirement accounts from big banks. Her campaign also said she “fought the tobacco companies to get more money for asbestos victims” when representing Falise v. American Tobacco Co.
