Brian D. Quintenz and Chris Brummer testified before the US Senate Committee on Agriculture, Nutrition and Forestry last week in support of their March 2016 nominations to become commissioners of the Commodity Futures Trading Commission. If approved by the full Senate, Mr. Quintenz, who founded Saeculum Capital Management, a CFTC-registered commodity pool operator, would replace former commissioner Scott O’Malia. Mr. Brummer, a professor at Georgetown Law School, would replace former commissioner Mark Wetjen.
