Donald Trump Jr was told by an interlocutor that he could get "very high level and sensitive information" that was "part of Russia and its government's support for Mr. Trump."
The 39-year-old Donald Jr -- who now runs the family real estate business in his father's stead -- responded "if it's what you say I love it" and set up a meeting with the source, according to the emails.
The email chain, released in its entirety by Donald Jr on his Twitter account, added fuel to the political firestorm swirling over allegations that Trump's campaign team colluded with Moscow to influence the 2016 election.
US intelligence agencies have concluded that Russian President Vladimir Putin approved a mass effort to tilt the election in Trump's favor, including hacking and leaking embarrassing emails from Democrats.
The email disclosure now thrusts the president's son at the center of multiple US investigations by Congress and by the FBI as to whether Trump's team was in the know.
Info to 'incriminate Hillary'
Donald Jr had initially dismissed the meeting he arranged with the Russian lawyer, Natalia Veselnitskaya, as having to do with adoptions, but then offered shifting explanations as more details emerged.
In the emails released Tuesday, Rob Goldstone -- a publicist close to the Trumps -- tells Donald Jr that he has learned of a Russian offer of compromising material on Clinton from a pop singer he represented, Emin Agalarov.
"The Crown Prosecutor of Russia met with his father Aras this morning and in their meeting offered to provide the Trump campaign with some official documents and information that would incriminate Hillary and her dealings with Russia and would be very useful to your father," Goldstone wrote in a June 3, 2016 email.
"This is obviously very high level and sensitive information but is part of Russia and its government's support for Mr. Trump - helped along by Aras and Emin," he added.
Donald Jr responded less than 20 minutes later, according to the chain of emails entitled "Russia - Clinton - private and confidential."
