TEHRAN (Tasnim)- Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei has slammed US senators� letter against a possible deal over Iran�s nuclear program saying it reveals the "collapse of US political ethics."







Ayatollah Khamenei also expressed concern about the �ploys� of the other side and said whenever the deadline for nuclear talks draws closer, they, particularly the Americans, toughen their tone.

Ayatollah Khamenei made the comments in a meeting with the chairman and members of the Assembly of Experts on Thursday.



His remarks came a few days after a group of 47 Republican senators wrote an open letter to the Iranian government, warning them that any nuclear deal they sign with US President Barack Obama's administration won�t last after Obama leaves office.

Imam Khamenei reiterated his support for the Iranian negotiating team in talks with six world powers over Tehran's nuclear program describing Iranian nuclear negotiators as �reliable and sympathetic individuals who are trying to secure the country's interests.�
