WASHINGTON (AP) — The Obama administration is weighing whether to offer Iran the chance to recoup billions of dollars in frozen overseas assets if it takes steps to scale back its nuclear program, U.S. officials and congressional aides said Friday. The proposal would face a skeptical Congress determined to make the end of Tehran’s uranium enrichment activity the condition for any sanctions relief.

The brainstorming comes after two days of nuclear negotiations between Iran and world powers ended this week in Geneva. The talks — the first since Iranian President Hassan Rouhani took office — ended on an upbeat note although it fell short of specific and concrete commitments by Iran to stop enriching uranium or ship out its stockpiles of higher-enriched uranium.
