There’s an article in the WSJ presumably providing more details. As reported by Reuters:
CFTC inspector starts probe into oil report: paper
Excerpt: "The Inspector General for the U.S. commodity-futures regulator has officially begun an investigation into an inter-agency report on commodity markets, the Wall Street Journal said citing a person close to the matter.
Earlier in the month four U.S. senators had sent a letter to Inspector General Roy Lavik questioning the Commodity Futures Trading Commission’s role in an inter-agency task force interim report that said "supply and demand factors" were responsible for the surge in fuel prices…
…The senators, including senior members of the Energy and Natural Resources Committee, allege that the CFTC knowingly included ‘seriously flawed’ data and the timing was ‘suspicious.’ The Inspector General was taking the issue "very seriously" and was conducting interviews in a number of CFTC offices…" More here.
Additional note: "The report was issued a few days before the Senate voted not to move forward on legislation that would have required the commission to set limits on trading in oil markets by investors and speculators. "The report, which specifically addressed speculation, appears to have been created and released to influence that Senate vote, which would be highly improper, in our view," wrote Sens. Ron Wyden of Oregon, Byron Dorgan of North Dakota, Maria Cantwell of Washington and Bill Nelson of Florida." Dems ask for probe into oil price report.
