US President Donald Trump told Russian officials that firing FBI director James Comey eased "great pressure" on him, US media report.
The New York Times, citing a document summarising last week's meeting, says he called Mr Comey a "real nut job".
Mr Comey had been running an inquiry into possible collusion between Russia and Donald Trump's election campaign.
The ex-FBI chief has agreed to testify before the Senate Intelligence Committee about the investigation.
The latest report was published just as Mr Trump took off on a flight to the Middle East for the first leg of his first foreign tour as president.
