There is no dispute that illegal naked shorting happens; what is in dispute is how much it happens, and to what extent is DTCC to blame. Some companies with falling stocks blame DTCC as the keeper of the system where it happens, and say DTCC turns a blind eye to the problem. Referring to trades that remain unsettled, DTCC's chief spokesman Stuart Goldstein said, "We're not saying there is no problem, but to suggest the sky is falling might be a bit overdone." In July 2007, Senator Bennett suggested on the U.S. Senate floor that the allegations involving DTCC and naked short selling are "serious enough" that there should be a hearing on them with DTCC officials by the Senate Banking Committee, and that banking committee chairman Christopher Dodd has expressed a willingness to hold such a hearing.
