Sen. Susan Collins (R-Maine) on Tuesday asked Goldman Sachs executives at the Senate Investigations Committee if they believed they had a duty to work on their clients' behalf. Joshua Birnbaum, former managing director at the bank, was the only witness to answer the question.
"Not only do I believe that we do, I believe that we did," he said.
The other executives either acted confused by the question or said their responsibility ended with supplying clients with rudimentary information about their investments.
Collins was visibly frustrated by the stonewalling. She also inferred that the witnesses were purposely slow in their response to keep from answering the questions posed by senators.
