Democratic presidential nominee Hillary Clinton's campaign declined on Friday to address quotes purportedly to be from private paid speeches she delivered to Wall Street banks, renewing questions about her transparency on the topics discussed at events that earned her hefty sums.

The quotes are in one of the 2,000 e-mails published Friday by WikiLeaks that the group described as having been hacked from Clinton campaign chairman John Podesta's Gmail account. Wikileaks, Podesta and the Clinton campaign declined to respond to repeated requests for comments about either the origin or veracity of the comments.

In the quotes, identified by Clinton aides for their potential political risk, she voiced support for "open trade and open borders" and discussed being "kind of far removed" from middle-class life. Clinton, who has long struggled to be seen as trustworthy by voters, also spoke about what she saw as the need to have "both a public and a private position" in politics to make deals and said that, for political reasons, Wall Street should be held accountable for the 2008 financial crisis.
