Clinton was responding to a question from CNN anchor Jake Tapper about "trust" issues. A recent CBS News poll reinforced what previous surveys have found — that Clinton lags far behind rival Bernie Sanders when voters are asked whether the candidates are "honest and trustworthy." The CBS poll showed a 17-point advantage nationally for the Vermont senator.
Throughout the race, Clinton has refused to concede any connection between her trust deficit and her use of a private email server as secretary of state; she has said repeatedly that voters don't care about the issue, even as the FBI conducts an investigation into the security of her practice.
Clinton made no such admission in the CNN interview, either. But in acknowledging that some voters question her motive in seeking the nation's highest office, she at least conceded that trust is a real hurdle she needs to clear.
