WASHINGTON: The US Senate advanced sweeping sanctions legislation targeting Russia's energy revenues Tuesday, as Ukrainian President Volodymyr Zelensky visited Washington to press for stronger action against Moscow. The bill would impose sanctions on Russian officials, oligarchs, financial institutions and the so-called shadow fleet used to evade restrictions on Moscow's oil exports. Supporters say choking off energy income is essential to weakening Russian President Vladimir Putin's ability to finance the war in Ukraine, now in its fifth year. The revised bill also extends existing sanctions authority aimed at restricting funding for Iran's energy and weapons sectors, which was added at Trump's request. The House has already left Washington for its summer recess and is unlikely to consider the bill before September.
