When Donald Trump Jr. met with a Russian lawyer in June 2016 at Trump Tower, he asked her for evidence that the Clinton Foundation had received illegal donations, according to a report Tuesday.

Natalia Veselnitskaya told the Senate Judiciary Committee that she did not have any information of that nature to provide to Trump Jr. and that he shortly became indifferent to the meeting afterwards, according to Veselnitskay's responses to Senate Judiciary Committee questions obtained by NBC News.

"Today, I understand why it took place to begin with and why it ended so quickly with a feeling of mutual disappointment and time wasted," Veselnitskaya wrote in a response to one question. "The answer lies in the roguish letters of Mr. Goldstone."

Rob Goldstone is a music promoter who arranged the meeting between Trump Jr., President Trump's eldest child, and Veselnitskaya. He works for the Agalarov family, Russian oligarchs with connections to the Kremlin who share business and social connections to the Trumps.

Emails between Trump Jr. and Goldstone show that Goldstone said Veselnitskaya had dirt on then-Democratic presidential candidate Hillary Clinton.

“If its what you say I love it especially later in the summer,” Trump Jr. said in response to one of Goldstone’s emails.

Veselnitskaya said she agreed to the meeting with hopes that the Trump team would look into the Magnitsky Act, which froze assets of Russian investigators and prosecutors and prevents them from entering the U.S. She said she did not discuss hacked or leaked emails, social media campaigns, or other areas concerning Russian interference in the 2016 election.

In addition to Trump Jr., former Trump campaign chairman Paul Manafort and President Trump’s son-in-law, Jared Kushner, were present at the meeting.

Manafort and his associate Rick Gates were indicted by a federal grand jury this fall on 12 charges related to the work they did in Ukraine before joining Trump's 2016 campaign, including conspiracy against the U.S., tax fraud, and money laundering.

The indictments were the first related to special counsel Robert Mueller’s investigation into Russian interference in the 2016 election and whether the Trump campaign colluded with the Kremlin.
