Hillary Clinton declined again to release transcripts of speeches she gave to major Wall Street banks, saying that she is being singled out.

Clinton's primary opponent, Sen. Bernie Sanders of Vermont, has pushed for Clinton to release transcripts of what she said before Wall Street firms such as Goldman Sachs. Clinton has since balked at the demand.

She downplayed any concern that the speeches would show her praising Wall Street's work.

"I don't have any concerns like that," she said. "I am concerned about the constantly changing set of standards for everybody else but me."

She said that it is a standard for candidates to release their tax returns but not transcripts from paid speeches.

"Now there is a new standard, and I said when it applies to everybody, you bet," Clinton said.

Sanders, who has railed against Wall Street since starting his campaign, has not given any paid speeches.
