US President Donald Trump has told Russia's foreign minister and ambassador that he is not interested in Moscow's interference in the 2016 election, The Washington Post reported.

Trump made the comments, which were not previously mentioned at the May 2017 meeting, in the Oval Office, in which he reportedly disclosed top-secret information about ISIS.

Trump told Russian Foreign Minister Sergei Lavrov and Ambassador Sergei Kislyak that he was not interested in their country's interference in the elections, given that the United States is doing the same in other countries, according to three former officials who asked not to be identified.

The meeting took place the day after Trump sacked then-FBI director James Komi, and the president told Russian officials that Komi's removal removed him from "heavy pressure." Trump's comments have alarmed White House officials, who have tightened restrictions on a memo about the meeting, limiting access to only those with high-level security powers.

The Washington Post report comes days after leaks rocked Washington over a phone call between Trump and Ukrainian President Volodymyr Zelinsky, and the person who leaked the call said the text was saved in a highly classified information system.

The leaked transcript said Trump urged Zelinski to investigate the son of Joe Biden, his leading Democratic opponent in the upcoming presidential election in 2020.

It was unclear whether the document, which contains details of Trump's meeting with Russian officials, was kept in the same system, but the New York Times reported yesterday that the White House had separately drafted Trump talks with sensitive topics with his Russian counterpart. Vladimir Putin, in the same system of top secret files, began the White House after leaks similar to Trump's speech in the Oval Office with Lavrov and Kislyak.

Trump's relationship with Russia has been subject to intense scrutiny since Trump came to power. Muller, Russian efforts to help Trump, and damage his Democratic rival, Hillary Clinton, in the 2016 presidential election.
