President Trump has gone to extraordinary lengths to hide details of his conversations with Russian President Vladimir Putin, including on at least one occasion taking possession of the notes of his own interpreter and instructing the linguist not to discuss what had transpired with other administration officials, current and former US officials said.
He noted that he had been holding one-on-one talks with the leaders of all countries without delegations, but "no one says anything about it".
And there is reportedly no record of his one-on-one, two-hour discussion with Mr Putin in Helsinki past year.

The New York Times reported that the probe began in the days after Mr Trump fired James Comey as director of the Federal Bureau of Investigation in May 2017 and said the agency's counterintelligence investigators had to consider whether Trump's actions constituted a possible threat to national security.
'And, obviously, nothing was found, ' Trump said of the alleged investigation.
'It was a great insult, and the New York Times is a disaster as a paper, ' Trump said.
The Washington Post report, published on Sunday, comes two days after the New York Times disclosed that the FBI had opened an investigation into Trump's relations with Russian Federation. "I couldn't care less". The publication claimed that even the classified USA files did not contain a single detailed record of conversations in five locations over the past two years.
He added: "Anybody could have listened to that meeting, that meeting is up for grabs". The whole Russian Federation thing it's a hoax, it's a total hoax, everybody knows it'. "Think about it, I have a one on one meeting with Putin like I do with every other leader, I have many one on one.nobody ever says anything about it but with Putin, they say 'oh, what did they talk about?' We talked about very positive things because look, we are beating everybody".More news: Winter weather advisory issued: Freezing rain possible for York, Lancaster, Chester
Such standard reactions from Trump "do nothing to address the incredibly serious nature of these allegations", said Democratic Congressman Jerrold Nadler, Chairman of the House Judiciary Committee.
What did the Washington Post report?
The Post writes that Trump had on at least one occasion taken the notes of his own interpreter and told them not to mention what had been talked about with Putin, according to current and former US officials.
It's unclear whether Trump has taken interpreters' notes on more than one occasion, but several officials told The Post they never received a reliable readout from Trump and Putin's meeting in Helsinki in July 2018, which no Cabinet officials or Trump aides attended. They spoke privately for two hours, accompanied only by their respective translators.
