Senator Kaufman delivered his final floor speech related to market structure issues on September 28, 2010. Beginning in July 2009, Kaufman had raised awareness and brought increased attention to problems with high frequency trading, dark pools, and flash orders. Kaufman left the Senate committed to continuing his work but convinced that American markets still lacked adequate transparency, regulation, and oversight. Senator Carl Levin (D-MI) spoke on the floor immediately following Kaufman and applauded Senator Kaufman’s “tireless” work for Delaware and the country. Levin vowed to pick up where Kaufman left off: “Although Senator Kaufman will soon be departing this body, we must continue his work so that those who seek to exploit our markets to the detriment of long-term investors and the real economy will not be able to do so without a battle from the Senate.”
