Paul Manafort, chair of the Donald Trump campaign, said on Wednesday morning that Trump still has no plans to release his tax returns despite questions about potential business dealings with Russian interests.

During an interview on CBS’ “This Morning,” co-host Norah O’Donnell noted that Trump has said that he does not have any investments in Russia.

“But does Russia have investments in Trump?” she then asked. “Would Mr. Trump be willing to release his tax returns to provide transparency on this issue?”

Manafort did not say whether Russia has invested in Trump, but said that the Republican nominee still has no plans to release his tax returns.

“Mr. Trump has said that his taxes are under audit, and he will not be releasing them,” he said. “It has nothing to do with Russia. It has nothing to do with any country other than the United States and his normal tax auditing processes.”
