Trial lawyers work to hold corporations accountable when they put profits over people and when government agencies fail to protect the public. A great example of this is shown in the video below of former trial lawyer Sen. Claire McCaskill as she relentlessly questions General Motors CEO Mary Barra. During this hearing at the Senate’s Subcommittee on Consumer Protection, Product Safety, and Insurance Sen. McCaskill exposes a key document that GM tried to hide. GM decided against fixing a defective ignition switch that would have cost only 90 cents per car.
