Democratic Debate: Clinton and Sanders Spar Over Wall Street Speech Transcripts

This has been a sticking point between the two opponents.

When asked by the moderators at the CNN debate, Clinton argued that there is no precedent to have presidential candidates release the transcripts of paid speeches, but if it becomes the new standard, she said that she would.

"There are certain expectations when you run for president. This is a new one," she said.

She has previously said she would be willing to release those transcripts "if everybody agrees to do it."

"There are speeches for money on the other side, I know that," she said.

He also said he would release his 2014 tax returns tomorrow.

He said that his wife Jane handled the paperwork and that they've been busy on the campaign trail. But he did go on to say that they will be released tomorrow.

"Look, I don't want to get anybody very excited," Sanders said. "They are very boring tax returns. No big money from speeches, no major investments. Unfortunately -- unfortunately I remain one of the poorer members of the United States senate. That's what that will show."
