'Letter' from Iran's Jalili

"...POLITICO has learned that Ashton received a letter from Iranian nuclear negotiator Saeed Jalili in late July/early August. But only one paragraph in what was described as a very long letter from Jalili dealt with the nuclear issue, a senior diplomat said Tuesday. 
Ashton responded to the paragraph in that letter in a communication back to Jalili to reiterate the desire of the international P5+1 group to resume talks with Iran about its nuclear program, the diplomat said. But as yet, she has not received a phone call from Jalili to schedule such a meeting.
Also on Wednesday, Clinton and Treasury Secretary Timothy Geithner will announce the designation of more entities that will be subject to Iran sanctions. Their joint announcement will take place at the State Department at 12:35 PM. ..."
