Jan. 6 Twitter witness: Failure to curb Trump spurred 'terrifying' choice [View all]

In an explosive hearing in July, an unidentified former Twitter employee testified to the House Jan. 6 committee that the company had tolerated false and rule-breaking tweets from Donald Trump for years because executives knew their service was his “favorite and most-used … and enjoyed having that sort of power.”

Now, in an exclusive interview with The Washington Post, the whistleblower, Anika Collier Navaroli, reveals the terror she felt about coming forward and how eventually that fear was overcome by her worry that extremism and political disinformation on social media pose an “imminent threat not just to American democracy, but to the societal fabric of our planet.”

“I realize that by being who I am and doing what I’m doing, I’m opening myself and my family to extreme risk,” Navaroli said. “It’s terrifying. This has been one of the most isolating times of my life.”

“I wouldn’t be doing this if I didn’t believe the truth matters,” she said.
