Donald Trump Jr. asked a Russian lawyer at the June 2016 Trump Tower meeting whether she had evidence of illegal donations to the Clinton Foundation, the lawyer told the Senate Judiciary Committee in answers to written questions obtained exclusively by NBC News.

The lawyer, Natalia Veselnitskaya, told the committee that she didn’t have any such evidence, and that she believes Trump misunderstood the nature of the meeting after receiving emails from a music promoter promising incriminating information on Hillary Clinton, Donald Trump’s Democratic opponent.

Once it became apparent that she did not have meaningful information about Clinton, Trump seemed to lose interest, Veselnitskaya said, and the meeting petered out.
