New York (CNN Business) Reading through the transcript on Friday of the testimony from Fiona Hill, President Trump's former top advisor on Russia, her commentary on our current information environment was striking. Hill spoke about the prevalence of internet conspiracy theories from fringe outlets like InfoWars, how some people who consume such content do happen to believe it, and how it was ultimately affecting United States policy.

None of what she said was new, of course. The Information Wars have been heavily covered for the last several years. But Hill's personal experience with the ramifications of misinformation and conspiracy theories (she's been a subject of many herself), in addition to her ability to connect the dots to policy decisions, made her testimony hit home.

"A mishmash of conspiracy theories"

During her testimony, Hill was asked about the removal of Marie Yovanovitch, the former ambassador to Ukraine, and why it marked a "turning point" for her. Hill said that it was because the accusations against Yovanovitch -- one being that she gave the fired Ukrainian prosecutor a "do not prosecute" list -- had "no merit whatsoever." In her words, it was "a mishmash of conspiracy theories."

Hill explained that such theories were the norm , noting that she had been the subject of similar ones. "My first year of my tenure at the National Security Council was filled with hateful calls, conspiracy theories," she said. Hill told House investigators that she has received death threats, calls at her home, a report of someone hammering on her door, and been accused of "colluding with all kinds of enemies of the President."
