John Bolton said Franklin D. Roosevelt met with Stalin at a time when “activity” in Russia was more brutal than it is in the 21st Century, and people who criticise the President risk having the historical memory of “fruit flies”.
Mr Bolton stated: “Franklin Roosevelt met with Joseph Stalin at a time when activity in Russia was a lot worse than it is today.
“I’m not excusing present conduct, but it didn’t seem to bother Franklin Roosevelt.
“And liberal Democrats weren’t bothered at the time when he met with Stalin.
“Let’s try and have some historical perspective here and not act like we have the attention span of fruit flies.”
Mr Karl had asked the White House figure whether Trump should be seen to meet with Putin when his track record on freedom of the press is so bad.
The presenter had questioned Mr Bolton: “Vladimir Putin and his government have jailed journalists.
“There have been accusations they have carried out murders of journalists critical of the Russian state.
“And we hear President Trump, doesn’t he kind of contribute to that authoritarian effort to undermine a free press when we hear him brand legitimate news organisations as fake? Legitimate news stories as fake?”
Mr Bolton dismissed the accusations and said Vladimir Putin had countered the claims.
He said: “I can tell you when I met with President Putin a few weeks ago to prepare for the Helsinki meeting, he made it plain that he said the Russian state was not involved.”
President Trump tweeted ahead of Helsinki meeting, slamming the news media and saying they would never be satisfied with the outcome of his talks with the leader of the Eastern superstate.
He posted on the social media network: “Heading to Helsinki, Finland – looking forward to meeting with President Putin tomorrow.
“Unfortunately, no matter how well I do at the summit, if I was given the great city of Moscow as retribution for all of the sins and evils committed by Russia…
“Over the years I would return to criticism that it wasn’t good enough – that I should have got Saint Petersburg in addition!
“Much of our news media is indeed the enemy of the people and all the Dems know how to do is resist and obstruct!
“That is why there is such hatred and dissension in our country – but at some point, it will heal!”
