On the morning of Sept. 16, 2008, the day the A.I.G. rescue was announced, Mr. Paulson's calendars show that he took a call from Mr. Blankfein at 9:40 a.m. Mr. Paulson received the ethics waiver regarding contacts with Goldman between 2:30 and 3 the next afternoon. According to his calendar, he called Mr. Blankfein five times that day. The first call was placed at 9:10 a.m.; the second at 12:15 p.m.; and there were two more calls later that day. That evening, after taking a call from President Bush, Mr. Paulson called Mr. Blankfein again.
When the Treasury secretary reached his office the next day, on Sept. 18, his first call, at 6:55 a.m., went to Mr. Blankfein. That was followed by a call from Mr. Blankfein. All told, from Sept. 16 to Sept. 21, 2008, Mr. Paulson and Mr. Blankfein spoke 24 times.
At the height of the financial crisis, Mr. Paulson spoke far more often with Mr. Blankfein than any other executive, according to entries in his calendars.
