Congressional aides said they expected Obama would sign the 10-year extension into law when it reached his desk.

US President Barack Obama is expected to sign US legislation extending sanctions against Iran for 10 years into law, the White House said on Friday.

“We believe the Iran Sanctions Act extension is not necessary, but we also believe it won’t interfere with the Iran deal,” spokesman Eric Schultz told reporters at a daily press briefing. “I would expect the president to sign this piece of legislation.”

The US Senate passed a 10-year extension of existing sanctions against Iran on Thursday. It passed the House of Representatives nearly unanimously in November, and congressional aides said they expected Obama would sign it when it reached his desk.

Iran’s Foreign Ministry said on Friday that the US Senate’s vote violated a historic nuclear deal reached between the country and six major powers in 2015.
