The White House on Saturday denied that President Donald Trump was briefed on reported U.S. intelligence that Russia's military offered bounties to Taliban-linked militants to kill U.S. troops in Afghanistan, with Democratic rival Joe Biden criticizing Trump for failing to take action against Moscow.

White House Press Secretary Kayleigh McEnany said in a statement that "neither the president nor the vice president (Mike Pence) were briefed on the alleged Russian bounty intelligence." The statement, McEnany said, did not address the "merit of the alleged intelligence" reported on Friday by the New York Times.

A Russian military intelligence unit linked to assassination attempts in Europe offered rewards for successful attacks last year on American and coalition troops, the Times reported. The newspaper reported that Islamist militants, or armed criminal elements closely associated with them, were believed to have collected some bounty money.
