Over the course of a year, Russian hackers ran a sophisticated campaign during the run-up to the 2016 US presidential election, infecting more than 30 computers and stealing more than 50,000 emails, in efforts to sway the vote in Donald Trump's favor.

On Monday, Trump met with Russian President Vladimir Putin, and denied the allegations, siding with the Russian leader over evidence the FBI presented. The White House didn't respond to a request for comment.
