Democrats denounce GOP letter on Iran nuke talks
WASHINGTON, D.C. - Democrats in the White House and Congress are accusing 47 GOP senators of undercutting President Barack Obama in international talks to curb Iran's nuclear program, saying that trying to upend diplomatic negotiations is tantamount to rushing into war with Tehran.
In a letter Monday to the leaders of Iran, Republican lawmakers warned that any nuclear deal they cut with Obama could expire the day he walks out of the Oval Office.
Vice President Joe Biden says the senators' attempt to undermine Obama offends him "as a matter of principle."
The letter comes as Obama and five world powers are in delicate negotiations to reach an initial agreement by the end of March to limit Iran's nuclear program.
Republicans say a deal would be insufficient and unenforceable.
