Legislation to impose new sanctions on Russia and Iran that passed the U.S. Senate nearly unanimously last week has run into a procedural problem that could prevent a quick vote in the House of Representatives, lawmakers said on Tuesday.

The Countering Iran's Destabilizing Activities Act, which also includes new sanctions against Russia, passed the Senate 98-2 last week, an overwhelming vote that looked like it might complicate President Donald Trump's desire for warmer relations with Moscow.

But the measure must still pass the House before it can be sent to Trump to sign into law, or veto, and the House parliamentarian found that the legislation violated a constitutional requirement that any bill that raises revenue for the government must originate in the House, something known as a "blue slip" violation.
