FLASHBACK: Trump Jr passed up chance to reveal 'everything' about Russia meeting 72 hours ago

Three days ago, Donald Trump Jr. appeared on Sean Hannity's show to claim that his release of emails between himself and publicist Rob Goldstone represented the full extent of his contacts about the Russian government's efforts to undermine Hillary Clinton's candidacy.

"This is all of it?" Hannity asked Trump Jr. about revelations about the meeting.

"This is everything," Trump Jr. insisted to Hannity.

However, Trump Jr. never mentioned that there was a fifth person in the room during his infamous meeting with Russian lawyer Natalia Veselnitskaya, along with Trump son-in-law Jared Kushner and former Trump campaign chief Paul Manafort.

Now NBC News' bombshell report has revealed that a former Russian counter-intelligence officer and current lobbyist was present shows that Trump Jr. was not being truthful when he insisted to Hannity that he had been totally transparent in recounting details about the meeting.
