Biden says he won't lift sanctions on Iran to bring country back to negotiating table

President Joe Biden said the US will not lift sanctions to get Iran back to the negotiating table, suggesting the measure would only happen if Tehran stops enriching uranium.
"No," Biden said when asked by CBS' Norah O'Donnell if he would make the move to start negotiations, nodding when she asked in a newly released interview clip if the country must stop enriching uranium first.
These comments mark the sharpest public response from the President on Tehran since taking office and continue a stalemate between the two countries.
