Another warning to the American oil industry regarding the supply of Russian diesel. Politico. Oil companies will be "held accountable" if they import at least one barrel of Russian diesel as part of President Donald Trump's deal with the Kremlin, one of the top members of the House Judiciary Committee, Jamie Ruskin, said in a letter to industry leaders. Ruskin, a Maryland Democrat expected to lead the powerful Judiciary Committee if Democrats win control of the House in next week's election, is the latest lawmaker to warn the industry against importing or scrapping any Russian fuel tied to U.S. sanctions. Ruskin sent a letter to the heads of industry trade associations - the American Petroleum Institute and the American Association of Fuel and Petrochemical Manufacturers. Another copy was sent to the head of the American Chamber of Commerce.
