The story has moved a long way from where it started in August, when Spitzer’s office began publicly investigating the possibility that Grubman’s 1999 upgrade of AT&T resulted in SSB getting a lucrative lead underwriting assignment for a major AT&T deal. Wednesday Gasparino rushed into print with a jumbled front-pager quoting a Grubman e-mail — quoting it repeatedly throughout the article, each time a little differently — suggesting that Weill had urged the upgrade as part of his power struggle with former Citi chairman John Reed. Lat Friday the story is that Grubman’s upgrade may have been a payback for Weill’s help in getting Grubman’s kids into an exclusive private nursery school.
