US President Donald Trump and Russian President Vladimir Putin held a meeting last year without a US translator or note-taker present, according to a report.
The Financial Times reported on Tuesday that the two leaders met on the sidelines of the G20 Summit in Argentina in November.
The newspaper cited a Russian government official who said the two leaders spoke for about 15 minutes about a number of foreign policy issues, including the Azov Sea incident, and the conflict in Syria.
The US president's wife Melania Trump and a Russian translator were reportedly the only other people present.

The White House had previously acknowledged that an "informal conversation" had taken place but did not offer further information.
The pair also reportedly discussed when a formal meeting could take place.
Mr Trump had cancelled bilateral talks at the summit after Russia attacked Ukrainian naval vessels in the Azov Sea.
It comes only weeks after the New York Times reported that the FBI had opened an investigation into whether Mr Trump was acting on Russia's behalf soon after he became president.
And Special Counsel Robert Mueller is currently investigating possible collusion between Mr Trump's 2016 election campaign and Russia.
Mr Mueller's team has indicted a total of 34 people - but so far, no charges of outright collusion between Mr Trump's campaign and Moscow have been filed.
But Mr Mueller has charged 12 Russian intelligence officers with hacking Democratic Party emails and 13 other Russians with engaging in an online campaign to influence US voters in the 2016 election.
