WASHINGTON - White House national security adviser Susan Rice on Saturday urged Congress to allow the United States to regain its vote at the United Nations Educational, Scientific, and Cultural Organization, which it lost for not paying dues."Shameful that US has lost its vote at #UNESCO," Rice wrote on Twitter. "Congress needs to fix this. Current law doesn't punish the Palestinians; it handicaps the US."UNESCO on Friday suspended the voting rights of the United States and Israel, two years after both countries stopped paying dues to the UN cultural arm to protest its granting full membership to the Palestinians.
