The media has gone nuts over the last couple days in regards to a June 2016 meeting between Donald Trump Jr., Jared Kushner, Paul Manfort and a Russian lawyer called Natalia Veselnitskaya. This reason for the uproar was that the premise of the meeting was the delivery of information by Veselnitskaya to the Trump team which incriminated Hillary Clinton in illegal activities with Russia. Don Jr. was initially approached with the idea by an acquaintance of his, Rob Goldstone, who set the meeting up. I go into the meeting in painstaking detail here.
The media has held this meeting up as a smoking gun for the Russian Collusion Theory which they have propagated for nigh on a year now. At the very least, they claim, it shows that the Trump campaign was willing to collude with Russia in order to influence the election.
