The SEC received a comment letter from Columbia Business School Professor Charles M Jones
https://www.sec.gov/comments/10-222/10222-433.pdf
but he never disclosed in that letter that in the past he had research that was supported by a grant from Citadel LLC. as stated in this press release.

That research was favorable to HFT.



I think it is important that the SEC and the public know this important piece of information and to know it is possible he was biased in his research because of prior support from Citadel who is against this IEX application.
