Forty-four U.S. senators sent a bipartisan letter to President Barack Obama urging him to cease negotiations with Iran if the country does not make three specific concessions regarding its nuclear program.

The letter, organized by Sens. Robert Menendez (D-NJ) and Roy Blunt (R-MO), said Iran must shut down the Fordo uranium enrichment facility near Qom, freeze all uranium enrichment above 5 percent, and ship all uranium enriched above 5 percent out of the country, Foreignpolicy.com reported.

“Absent these steps, we must conclude that Tehran is using the talks as a cover to buy time as it continues to advance toward nuclear weapons capability. We know that you share our conviction that allowing Iran to gain this capability is unacceptable,” the letter said.
