A former federal prosecutor said the 37-page indictment of 13 Russians for allegedly interfering in the 2016 election reveals how well-coordinated, organized and effective Moscow's “information warfare” campaign was.

The indictment, signed by Special Counsel Robert Mueller, charges the defendants with conspiracy to defraud the United States, three defendants with conspiracy to commit wire fraud and bank fraud and five defendants with aggravated identity theft.

"They were playing the long game, and if this wasn't disrupted, certainly this would have continued going forward," Jeffrey Cramer said on "Shepard Smith Reporting" on Friday, describing the conspiracy as "very well-constructed, very well-funded and very well-executed."

Shep pointed out that the scheme apparently involved setting up hundreds of social media accounts using stolen or fictitious identities to pose as politically-active Americans and recruit “real Americans” to stage rallies and engage in political activities.

Cramer lamented that many Americans were "easy dupes," not only in going to events that were organized and funded by Russians but also in spreading on social media information that originated with a foreign entity.

"If it wasn't so tragic, it would be comical," he said. "I think we were our own worst enemy here."
