Three US Senators—Maria Cantwell, Dianne Feinstein and Carl Levin—penned a letter to Commodity Futures Trading Commission Chairman Timothy Massad, complaining about the recent CFTC settlement with Brian Hunter, a former trader at Amaranth Advisors, LLC. Last month, the CFTC settled an enforcement action against Mr. Hunter related to his involvement in an alleged attempted manipulation of natural gas futures contracts on two days in 2007 for payment of a fine of US $750,000. The three senators termed the settlement “an embarrassment” for being too low.
