In October, WikiLeaks sent Trump jnr a message: "Btw we just released Podesta Emails Part 4." It provided him with a link. Two days later, on October 14, 2016, Trump jnr tweeted out the link.
WikiLeaks asked for Trump's tax returns, which the President has refused to release. Trump jnr did not respond.
WikiLeaks wrote: "If we publish them it will dramatically improve the perception of our impartiality. That means that the vast amount of stuff that we are publishing on Clinton will have much higher impact, because it won't be perceived as coming from a 'pro-Trump' 'pro-Russia' source".
In December, WikiLeaks wrote: "In relation to Mr. Assange: Obama/Clinton placed pressure on Sweden, UK and Australia (his home country) to illicitly go after Mr. Assange. It would be real easy and helpful for your dad to suggest that Australia appoint Assange ambassador to [Washington,] DC."
The WikiLeaks Twitter account sent a direct message to Trump jnr in September 2016, telling him that an anti-Trump site run by a political action committee was "about to launch".
"The PAC is a recycled pro-Iraq war PAC. We have guessed the password. It is 'putintrump.' See 'About' for who is behind it. Any comments?" WikiLeaks wrote, the Atlantic reported. "Off the record I don't know who that is, but I'll ask around," Trump jnr said.
WikiLeaks asked Trump jnr to "push" a story in conservative media that alleged Clinton joked about wanting to "drone" its founder Assange. Trump jnr responded that he "already did that earlier today".
A lawyer for Trump jnr, Alan Futerfas, told the Atlantic: "we can say with confidence that we have no concerns about these documents and any questions raised about them have been easily answered in the appropriate forum."
Trump jnr met a Russian lawyer at Trump Tower last June that he said he went to after being offered damaging information on Clinton.
