"I don't think the transcripts — they don't mean very much to me," Trump said during a phone interview with Fox News's Greta Van Susteren. 
"What really means something are the 33,000 emails that she deleted, that's what I think she should be giving up," Trump said, referring to emails Clinton erased from the private server she used when she was secretary of State.
"I would be very interested, but not with transcripts. I'm not interested in her transcripts. I'm much more interested in her emails."
Clinton was pressed during the Democratic presidential primary to release her Wall Street speeches, while Democrats and some top Republicans called on Trump to release his taxes.
Trump's campaign chief said Wednesday that Trump "will not be releasing" his taxes despite the candidate's past vows to release them once an IRS audit was complete.
"Most people don't care about it," Trump stated Thursday, saying he's had "very little pressure" to release them. 
Clinton, along with former GOP nominee Mitt Romney, has for months called on Trump to release his tax information. Romney himself faced pressure in 2012 to release his returns and eventually did.
"After he gave it, they found a little sentence and they made such a big deal. He might have lost the election over that," Trump said Thursday.
"His is a peanut compared to mine," Trump added of Romney's tax returns.
Trump rebuffed questions about releasing his tax returns for previous years when pressed by Van Susteren.
The GOP nominee has pointed to Van Susteren, who previously said that as a lawyer, she would not recommend releasing taxes under audit. The IRS has said it has no rule against such a release.
