CrowdStrike, the private cyber-security firm that first accused Russia of hacking Democratic Party emails and served as a critical source for U.S. intelligence officials in the years-long Trump-Russia probe, acknowledged to Congress more than two years ago that it had no concrete evidence that Russian hackers stole emails from the Democratic National Committee's server.

CrowdStrike President Shawn Henry's admission under oath,  in a recently declassified December 2017 interview before the House Intelligence Committee, raises new questions about whether Special Counsel Robert Mueller, intelligence officials and Democrats misled the public. The allegation that Russia stole Democratic Party emails from Hillary Clinton, John Podesta and others and then passed them to WikiLeaks helped trigger the FBI's probe into now debunked claims of a conspiracy between the Trump campaign and Russia to steal the 2016 election.
