Obama to update Senate leaders on Iran talks on Tuesday

WASHINGTON (Reuters) - President Barack Obama will meet with Senate leaders from both parties on Tuesday to try to convince them not to adopt further sanctions on Iran as the United States and other world powers head for new nuclear negotiations with Tehran, the White House said.

Obama urged Congress last week to hold off on new sanctions and sought to reassure lawmakers that any easing would be modest and could be quickly reversed if Iran shows it is not serious about curbing its nuclear program.
