Bloomberg's Timothy O'Brien spotlighted the potential significance of Weisselberg's implication in the whole thing shortly after the Cohen-Trump tape came out Tuesday evening.
O'Brien would probably be familiar with Weisselberg, since he handled Trump's finances. In 2005, O'Brien was sued for libel over his book that said Trump was not a billionaire.
Eventually, that led to O'Brien getting access to Trump's tax records as part of discovery. He's still under NDA constraints not to discuss what he saw.
