President Trump is denying a New York Times report that he was briefed on an alleged Russian effort to pay bounties to Taliban-linked militants to kill Western forces — including U.S. troops — in Afghanistan.

Citing unnamed officials, the Times report, published Friday, details how U.S. intelligence officials reached the conclusion about the secret payments and then briefed the president in March. The White House National Security Council conferred an inter-agency meeting that same month to discuss the matter, according to the report. The finding was also included in the President's Daily Brief, according to the Times.

President Trump denied the report in a series of tweets on Sunday, saying he was never briefed on the intelligence assessment.

"Nobody briefed or told me, @VP Pence, or Chief of Staff @MarkMeadows about the so-called attacks on our troops in Afghanistan by Russians, as reported through an "anonymous source" by the Fake News @nytimes Everybody is denying it & there have not been many attacks on us....," Trump said.

The president followed-up the denial by saying "Nobody's been tougher on Russia than the Trump Administration." He went on to criticize former President Obama, the Times, presumptive Democratic nominee Joe Biden and his son Hunter.

"With Corrupt Joe Biden & Obama, Russia had a field day, taking over important parts of Ukraine - Where's Hunter? Probably just another phony Times hit job, just like their failed Russia Hoax. Who is their 'source'?" Trump tweeted.

The White House denied on Saturday that the president had been briefed on the matter, but as the Times notes, press secretary Kayleigh McEnany did not push back on the substance of the intelligence assessment.

A statement Saturday by John Ratcliffe, the director of national intelligence, also denied that the president was briefed on the issue, but also did not refute that Russia had offerred bounties in exchange for attacks on U.S. forces.

The Times, in its reporting, does not specify how many troops may have been killed by insurgents seeking monetary reward, but does say officials were confident that Russian operatives offered and paid bounties to militants for killing Americans. In a separate report by CNN, an unnamed European intelligence official said Russia also offered bounties for the killing of soldiers from the U.K.

According to the Times, U.S. officials have concluded that the bounty operation was orchestrated by the G.R.U., an arm of Russian military intelligence that has been linked to assassination attempts and other cloak and dagger operations, including the 2018 nerve agent poisoning of a former Russian spy in Salisbury, England.

The G.R.U. is the same unit that U.S. intelligence has implicated in efforts to sway the 2016 presidential election.

The Russian embassy in Washington denied the Times report in a tweet on Saturday, calling the report "fake news." A spokesman for the Taliban told the newspaper the report was "baseless."

Critics of President Trump called the reporting further evidence that the president has failed to adequately curb the influence of Russia, and instead sought to foster a cozy relationship with Russian President Vladimir Putin.

Speaking from a virtual town hall on Saturday, former Vice President Biden said that if the the story was correct, then it was a betrayal to U.S. forces to fail to protect them in a war zone.

"Not only has he failed to sanction or impose any kind of consequences on Russia for this egregious violation of international law, Donald Trump has continued his embarrassing campaign of deference and debasing himself before Vladimir Putin," Biden said.

In another tweet Sunday, Trump responded by calling his likely 2020 opponent corrupt and his comments on the Times story, "obviously written by his handlers."
