Donald Trump Jr.'s eagerness to meet a year ago with a Russian government lawyer offering damaging information on Hillary Clinton has produced a political firestorm for the White House.

But it's not clear just how much legal liability the disclosure presents for President Donald Trump's son.

A series of emails posted to Trump Jr.'s Twitter account, detailed an exchange with Rob Goldstone, a publicist who helped to arrange the June 9, 2016, meeting with Natalia Veselnitskaya.

The email thread makes clear that presidential candidate Trump's eldest son was eager to gather "opposition research" from the lawyer as part of Russian government support for his father. But the meeting apparently ended without any such information being offered.

Veselnitskaya has said she is a private lawyer and denies having Kremlin ties. But she told NBC News the Trump campaign was eager to gather damaging information on Clinton.

"It's quite possible that maybe they were looking for such information, they wanted it so badly," she said through a translator.
