Bart Chilton, former commissioner of the Commodity Futures Trading Commission and one of the CFTC’s most vocal investor protection promoters during the development of the Dodd-Frank Act, has become a high-frequency-trading lobbyist.

The Modern Markets Initiative said Thursday that its hiring of Chilton and his Washington law/lobbying firm, DLA Piper, marks the beginning of an expanded mission for the trade group.

“The role and benefits of high-frequency-trading are misunderstood by many,” said Chilton in an MMI press release. “Through education, transparency and the right type of constructive regulation, HFT’s role will be accepted and endorsed as essential to today’s modern markets. The U.S. markets are the envy of the world and we must keep them that way.”
