A bipartisan group of six US senators calls on President Donald Trump to “immediately reverse course” on a plan to buy Russian diesel, arguing the move conflicts with US legal restrictions. The senators say the administration’s approach does not align with a statute that bars Russian energy imports unless Russia ends its aggression against Ukraine.

According to multiple outlets, four Republican senators and two Democratic senators signed the statement released Sunday. They criticize the administration for allegedly failing to consult Congress and for not providing an explanation justifying the decision as required by law. The outlets also note the deal is framed by the administration as a way to help lower high fuel prices, with Russia set to provide roughly 800,000 tons of diesel over about two months.

While the reports agree on the senators’ demand and their stated legal rationale, they differ mainly in wording and emphasis: some focus on the bipartisan nature of the backlash, while others stress the requirement for congressional consultation and the statutory basis for opposing the purchase.
