A bipartisan group of six senators are calling on President Donald Trump’s administration to “immediately reverse course” on a plan to purchase diesel from Russia as part of an effort to lower high fuel prices. Four Republican senators and two Democratic senators signed onto the statement released Sunday in protesting the deal. They said the administration failed to consult with Congress or submit any explanation to justify its decision as required by statute. They said the United States should not provide Russian President Vladimir Putin with a financial lifeline while Russia continues to kill Ukrainian civilians.
