The Senate Judiciary Committee's release Wednesday of the Trump Tower transcripts and hundreds of pages of exhibits provide the most comprehensive view yet into the circumstances surrounding the controversial meeting and the details of the roughly 20-minute encounter, in which Trump's team was expecting dirt from Veselnitskaya. Trump Jr. told both House intelligence committee and Senate Judiciary Committee investigators that he spoke with someone who had a blocked number but that he couldn't remember whom.
But the day after the blocked call - and two days before the Trump Tower meeting - the elder Mr Trump announces that he would be making a "major speech" the following week "discussing all of the things that have taken place with the Clintons".
Donald Trump Jr. shut down the June 2016 meeting at Trump Tower by telling his Russian guests perhaps they'd revisit the discussion about lifting sanctions legislation should his father win the election.
The BBC's Anthony Zurcher: Mr Trump Jr's "If it's what you say, I love it" email was one of the most explosive revelations when news of the June 2016 Trump Tower meeting was first made public. Trump Jr. said that he neither offered his father advance warning that he'd been invited to learn about Russian government "dirt" on Clinton, or informed him after the fact that the conversation had instead mostly focused on reinstating a program allowing Americans to adopt Russian children. That offer does not appear to have translated into an actual digital campaign.
In his Senate interview, Mr Trump Jr called his use of the phrase a "colloquial term" to say "great, thank you" for "potential information about an opponent" - namely, Hillary Clinton. "I knew of something", said Trump Jr. "The public can now see that for over five hours I answered every question asked and was candid and forthright with the committee". He did so after receiving emails that described an outreach, via a series of intermediaries, from Russia's top federal prosecutor, Yuri Chaika, offering help to the Trump campaign.
The transcripts show the dissatisfaction of Trump Jr. and other campaign aides, including brother-in-law Jared Kushner, when the meeting failed to yield the harmful Clinton information they thought they'd get - as well as the increasing panic of one of the meeting participants who feared his reputation would be ruined for his role in having set it up.
Members of Congress and the Justice Department are investigating.
In January, Senate Judiciary Chairman Chuck Grassley said he planned to release the transcripts because the committee's interviews connected to the Trump Tower meetings had wrapped up. Mark Warner, D-Va., said Wednesday in a joint statement with Sen.
But that last determination - that Russian Federation meant to help Trump - sets up a clash within the GOP over which record of events is most accurate, a dispute that could complicate the party's messaging surrounding the Russian Federation investigations as it heads into the 2018 election season.
The House intelligence committee cited Trump Jr.'s denials in completing its report about the Russia imbroglio with a finding that there had been no collusion between the Trump camp and the Russian active measures.
The allegations, and multiple investigations into the matter, have shadowed the first 16 months of Trump's presidency.
