"WikiLeaks," Donald Trump said at a campaign rally on Oct. 10, 2016. "I love WikiLeaks."

That was three days after U.S. intelligence agencies issued a public warning that the Russian government was using the organization, already well known for its disclosures of government secrets, to interfere with the presidential election.

Now special counsel Robert Mueller has charged longtime Trump adviser Roger Stone with attempting to undermine government investigations by lying about his links between Trump's campaign and WikiLeaks.
