Trump blocks Russia sanctions, cites national interests amid Zelensky row

US President Donald Trump invoked executive authority to block multiple Russia sanctions passed by Congress, citing national interests. The move delays implementation of the Lindsey Graham sanctions law, which targets the Russian economy and includes penalties on Russian oil and gas purchasers. This decision follows Trump's announcement to import Russian diesel and comes amid intensifying tension with Ukrainian President Volodymyr Zelensky, who called the diesel deal a gift to Putin.
