At the press conference, Putin made several deliberate and perhaps deliberately very weak lies concerning D. Trump, here below is the first one (the second concerned Putin's denial that the KGB or the FSB would ever be interested in D. Trump prior to his presidential campaign):
Putin: I heard about us allegedly collecting dirt on Mr Trump when he was in Moscow. Colleague, when Mr Trump came to Moscow, I was not even aware that he was there. I respect President Trump as head of the United States, but when he came here as a businessman, I was not even aware that he was in Moscow.
"In November 2013, Trump traveled to Moscow for the Miss Universe pageant, which he co-owned at the time and which was hosted by Russian real estate developer Aras Agalarov and his son, Emin. Trump’s eager anticipation of this trip was exemplified in a June 2013 tweet, in which he asked: “Do you think Putin will be going to The Miss Universe Pageant in November in Moscow – if so, will he become my new best friend?” http://en.kremlin.ru/events/president/news/58017
At the March 2014 Conservative Political Action Conference, Trump spoke about receiving a gift from Putin, saying “Putin even sent me a present, beautiful present, with a beautiful note. I spoke to all of his people. And, you know, you look at what he’s doing with President Obama. He’s, like, toying with him. He’s toying with him.” He praised Putin again in March 2014, saying “I was in Russia, I was in Moscow recently. And I spoke indirectly—and directly—with President Putin, who could not have been nicer.”
