In the interview, Putin also pushed back against suggestions that Russian Federation may have compromising material about Trump, saying "it's clear that we did nothing of that kind of against Mr. Trump".
He added that Mr Putin suggested the USA should provide its intelligence to the Russian military so Russia can determine the truth of what happened. He and Putin seemed to be speaking from the same script as the president made a conscious choice to defend a tyrant against the fair questions of a free press, and to grant Putin an uncontested platform to spew propaganda and lies to the world.
When asked by a reporter whether he believed the various USA institutions that asserted Russian interference or Vladimir Putin, Trump did not provide a direct answer.
With attempts to reset relations with Russian Federation by former presidents George W. Bush and Barack Obama, Browder said appeasement simply doesn't work with a criminal like Putin. I will say this: I don't see any reason why it would be, but I really do want to see the server.
Trump also attacked special counsel Robert Mueller's investigation, calling it "a disaster for our country".
Trump and Putin held a private, one-on-one meeting that lasted two hours, CBS News reported.
Trump responded, "I have great confidence in my intelligence people, but I will tell you that President Putin was extremely strong and powerful in his denial today". "However, I also recognise that in order to build a brighter future, we can not exclusively focus on the past - as the world's two largest nuclear powers, we must get along!"
It certainly did. With his remarks in Helsinki and at the North Atlantic Treaty Organisation summit in Brussels, Trump has signaled a historic shift in USA foreign policy that may determine the future of this nation and the fate of his presidency.
First District Democratic Representative Chellie Pingree says the summit was "shameful", with Trump downplaying Russian attempts to influence USA elections just days after a dozen Russian intelligence agents were indicted for those attempts.
Astonished Republicans and Democrats uniformly condemned Trump, with harsh criticism coming even from hosts on Fox News - a network normally friendly to the president.
Coat's predecessor, James Clapper, called Trump's acquiescence to Putin "an incredible capitulation", while former Central Intelligence Agency chief John Brennan labelled it "nothing short of treasonous".

"We've known for years that the Russians routinely try and influence USA elections", he said.

"We don't have anything on them, and there can't be anything on them", Putin said.
The two leaders appeared relaxed at the Helsinki news conference, smiling on occasion, in contrast to their sombre demeanour at the start of the day.
Trump told CBS Evening News anchor Jeff Glor that he had low expectations for the summit. "It is unfortunate that President Putin refuses to acknowledge these facts". Trump touted the summit as a chance to improve ties.
Looking back over the week, from Brussels to Britain to Helsinki, Trump's message has been clear, consistent and startling.
Trump also received backlash for the comments from his own party.
Former Vice President Joe Biden.
Presidents Putin and Trump will meet today at the Presidential Palace in Helsinki. American presidents must be the champions of that cause if it is to succeed.
"The President must appreciate that Russian Federation is not our ally", Mr Ryan said in a statement.
In a strongly-worded statement, Mr Ryan said: "There is no moral equivalence between the United States and Russian Federation, which remains hostile to our most basic values and ideals".
"The administration should proceed with caution in dealing with Putin and should hold Russian Federation accountable for their attacks on democratic societies and institutions", he said in a statement.
