President Donald Trump on Friday signed into law the Lindsey O. Graham Sanctioning Russia and Iran Act, the White House said, two days after the House passed the package 262–159 and following an 86–11 Senate vote in August.

The legislation targets Russia’s energy and defense industries and its sanctions-evading “shadow fleet,” and grants the president significant new power to levy steep tariffs—described in analyses as up to 100%—on countries facilitating Russian sanctions evasion. Iran-related provisions were added during negotiations after Trump pushed to broaden the bill.

Named for the late Sen. Lindsey Graham, who died in July, the Act drew bipartisan support but also warnings that tariff authorities could spark wider trade conflicts. The Kremlin had said Thursday that signing would complicate Ukraine peace efforts.

Wires agree on the Friday signing and core authorities; markets and allies will now watch which tariff targets Trump picks first.
