Senators unanimously approved an amendment Thursday that backs bolstering sanctions against Iran if President Obama can't verify that the country is following a nuclear deal. 

The Illinois Republican's amendment originally supported restoring rolled-back sanctions, as well as applying new sanctions, if Iran violated the interim deal currently in place or a long-term agreement on its nuclear program. 
The final amendment supports reimposed and new sanctions against Iran if Obama "cannot make a determination and certify that Iran is complying" with an agreement. 
The amendment establishes a "deficit-neutral reserve fund," meaning that it can't add to the deficit, and is nonbinding, but it does get senators on the record on Iran sanctions.
