On Russian bounties, what did Trump know and when did he know it?

It was late Friday when the New York Times first reported on a stunning story: according to U.S. intelligence, while peace talks were underway to end the long-running conflict in Afghanistan, a Russian military intelligence unit "offered bounties to Taliban-linked militants for killing coalition forces in Afghanistan -- including targeting American troops."

Soon after, most of the nation's leading news agencies confirmed the story: U.S. intelligence agencies have reason to believe Vladimir Putin's government offered financial rewards to those who killed American servicemen and women.

Among the many questions is when, exactly, Donald Trump learned of the allegations. The initial reporting indicated that the information reached the Oval Office three months ago. In an overnight report, the NYT updated the timeline: despite White House efforts to say the American president was clueless, administration officials indicated that Trump was presented with the information in writing in February.
