The White House is confident it can still pursue Iran nuclear talks despite U.S. Secretary of State John Kerry's injury over the weekend.
Kerry left Europe for the United States earlier on June 1 after breaking his leg in a cycling accident a day earlier in Switzerland.
White House spokesman Josh Earnest told reporters in Washington on June 1 that Kerry would continue to play a critical role in the talks, although it was unclear exactly what his capacity to participate would be in the coming weeks.
Kerry was in Geneva for six hours of nuclear negotiations with Iranian Foreign Minister Mohammad Javad Zarif on May 30.
World powers and Iran are trying to seal a comprehensive accord by June 30.
