The US House of Representatives approved the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 in a 262-159 vote. This legislation targets Russia's shadow fleet of tankers and penalizes Moscow's banks, oligarchs, and senior officials. President Donald Trump signs the measure into law on September 18, completing the legislative process after a Senate approval last month.

The act extends the Iran Sanctions Act of 1996 through 2031 and adds restrictions on Iran's aviation and weapons sectors. India's foreign ministry responded to the passage by stating the nation will continue diversifying energy sources to ensure supply security. This legal framework grants the US president authority to impose 100% tariffs on the five largest buyers of Russian oil and natural gas.
