"U.S. to Review Claims Oil Companies Undercut Renewables"

"The U.S. Federal Trade Commission said it will examine allegations that oil companies may be undermining efforts to distribute renewable fuels."

"The FTC will 'evaluate' concerns that oil companies are blocking the distribution of renewable fuels by requiring retailers to carry premium gasoline, commission chairwoman Edith Ramirez said in a letter released today by two U.S. lawmakers who had called for an inquiry.

Senators Charles Grassley, an Iowa Republican, and Amy Klobuchar, a Minnesota Democrat, earlier this month asked the Justice Department and the FTC to investigate whether oil companies are violating federal antitrust law by blocking the introduction of higher ethanol blends of gasoline."
