At the time of that video, we didn't know about the June 9, 2016 meeting at Trump Tower involving Donald Trump Jr., Paul Manafort (the Trump campaign manager at the time) and Jared Kushner with Natalia Veselnitskaya and several other Russian operatives. Therefore, we also didn't know at the time that Trump himself, would lie about who was in attendance at that meeting and what was discussed. At first, it was just about the Magnitsky Act and Russian adoptions. Now, because of the existence of incriminating e-mails between Donald Trump Jr. and Rob Goldstone, Trump has admitted that the meeting was about obtaining dirt on Hillary Clinton.
So, in other words, yes ... things have happened in the last 15 months to support collusion between the Russians and the Trump campaign.
