Republican US Senator Thom Tillis expressed concerns on Sunday regarding President Donald Trump’s recently announced diesel supply deal with Russia, suggesting it may be illegal. He further warned the arrangement poses a risk to American lives. President Trump announced on Friday that Russia agreed to supply diesel to global markets, prompting his administration to temporarily lift US sanctions on Russian fuel. These sanctions were originally implemented to limit Moscow’s revenue streams used to fund its war on Ukraine. Tillis’s criticism joins a growing wave of bipartisan opposition to the deal. The senator's statement adds further scrutiny to the administration's decision, questioning the legal and strategic implications of circumventing existing sanctions against Russia. This move is likely to face continued debate as concerns surrounding the Ukraine conflict persist.
