The Washington Post analyzed the interview, and determined that during the 30 minute interview Trump lied 24 times.
Perhaps the most egregious claim was that there was no collusion with Russia by members of the Trump campaign, and in fact it was the Democrats who colluded. The truth is totally the opposite. Certainly arrests have already been made of Paul Manafort, Rick Gates, Michael Flynn, (to which he plead guilty), and George Papadopolous (to which he plead guilty), all of whom worked on the Trump campaign, and none of whom are Democrats.
The fact that two of the four have plead guilty is evidence of collusion. The only remaining question is whether Trump himself was part of the collusion.
