Also in 2018, emails documenting Ferguson's attempts to discredit a progressive activist student at Stanford University who had been critical of Ferguson's choices of speakers invited to the Cardinal Conversations free speech initiative were released to the public and University administrators. He teamed with a Republican student group to find information that might discredit the student. Ferguson resigned from leadership of the program once university administrators became aware of his actions. Ferguson responded in his column saying, "Re-reading my emails now, I am struck by their juvenile, jocular tone. “A famous victory,” I wrote the morning after the Murray event. “Now we turn to the more subtle game of grinding them down on the committee. The price of liberty is eternal vigilance.” Then I added: “Some opposition research on Mr O might also be worthwhile”—a reference to the leader of the protests. None of this happened. The meetings of the student committee were repeatedly postponed. No one ever did any digging on “Mr O”. The spring vacation arrived. The only thing that came of the emails was that their circulation led to my stepping down."
