The president came under widespread criticism on Monday for not backing his intelligence community's assessment that Moscow had interfered in the presidential election and blamed America for the deteriorating relations with Russian Federation.
Trump has come in for bipartisan criticism for what many saw as his unsettling embrace of the Russian strongman this week - and his seeming disavowal of his own intelligence agencies and their assessment that Moscow meddled in the 2016 election.
Coats said he was also not aware of the content of the private the president's private conversation with Vladimir Putin Helsinki. "I will say this: I don't see any reason why it would be".
Coats also appeared to be caught by surprise on a major White House announcement: that Trump had invited Putin to visit Washington in the fall - the first such visit in almost 13 years.
The announcement appeared to come as a surprise to US Director of National Intelligence Dan Coats, who was told about it during a live interview at the Aspen Security Forum in the state of Colorado.
Trump had praised the proposal on Monday as an "incredible offer" and Sanders later described it as an "interesting idea" that was being discussed internally. "In a key sentence in my remarks I said the word "would" instead of "wouldn't", Trump said in an extraordinary postcript to the Helsinki conference on Tuesday.
The White House rejected Mr Putin's offer as the Republican-controlled Senate issued a rebuke to Mr Trump by going on record against the offer.
It is this hostility toward Russian Federation that has driven bilateral ties to their worst point since the height of the Cold War, and has them resisting even the hint of detente.
He also learned of Mr Trump's decision to invite Mr Putin to Washington for a second meeting this autumn while he was being interviewed at the Aspen forum.
How did Trump respond to Putin's suggestion?
On Thursday, the Trump administration poured cold water on at least one proposal from Putin: that Russia be allowed to interview Americans the Kremlin accused of crimes - the quid pro quo for allowing US investigators to interrogate Russian intelligence officials recently indicted in the USA for alleged election interference.
"It is a proposal that was made in sincerity by President Putin, but President Trump disagrees with it". With confusion still swirling around what the two men discussed behind closed doors in Helsinki earlier this week, Ambassador Anatoly Antonov said it's important to "deal with the results" of their first summit before jumping too fast into a new one.
At the news conference with Putin, he was asked if he would denounce what happened in 2016 and warn Putin never to do it again, and he did not directly answer.
He meant to say, "I don't see any reason it wouldn't be Russian Federation".
"We will see how things develop further", Putin said, evoking unnamed "forces" in the USA trying to prevent any improvement in relations and "putting narrow party interests above the national interest".
