Appearing on CBS This Morning, Donald Trump's top aide said the candidate will not be releasing his tax returns as he sidestepped questions about Trump's financial ties to Russia.

"Mr. Trump has said that his taxes are under audit and he will not be releasing them," campaign chief Paul Manafort stated. "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 process."

Trump's finances were previously under scrutiny -- as are all candidates for the presidency -- however the interest has ratcheted up since questions about Russian investments moved to the forefront.

Asked about Russian money, Manafort deferred to statements Trump previously made.

"So to be clear, Mr. Trump has no financial relationships with any Russian oligarchs?" Manafort was asked.

"That’s what he said, that’s what I said," Manafort replied. "That’s obviously what our position is."

Trump has denied having relationship with the Russian government.
