Hillary Clinton weighed in on the controversy over “fake news” Thursday calling it “a threat that should concern all Americans, Democrats, Republicans, and independents alike.”

Speaking at the unveiling of a portrait of Senator Harry Reid (D-NV) in Washington, D.C., Clinton said “malicious fake news and false propaganda” are an “epidemic” that “flooded social media over the past year,” adding:

“It's now clear that so-called fake news can have real-world consequences. It's a danger that must be addressed and addressed quickly.”

The most visible examples of the “fake news” occurred Sunday when a 28-year-old North Carolina man entered a Washington, D.C. pizza restaurant with a firearm to “self-investigate” a false conspiracy that it was actually a front for a child sex ring run by Clinton and members of her campaign. The man found no evidence and was arrested.

Clinton said efforts to combat fake news should involve both public and private efforts. A bipartisan bill to combat foreign propaganda has introduced by Senators Rob Portman (R-OH) and Chris Murphy (D-CT), which Clinton referenced, and she also said, “Silicon Valley is beginning to grapple with the challenge.”
