From the Wall Street Journal -

"Two investors who are part of Larry Silverstein's group that owns the World Trade Center lease are among the buyers of the Sears Tower, which MetLife Inc. agreed to sell Thursday for more than $800 million, according to people familiar with the situation.

Lloyd Goldman and Joseph Cayre, New York investors who are among Mr. Silverstein's backers in the Trade Center, are part of a group that agreed to buy the Chicago landmark, these people said. Another New York investor, Jeffrey Feil, was also a participant in the Sears Tower deal, the people said. Names of the other investors couldn't be learned."

Note that the two individuals are listed as part of a group that agreed to buy the Sears Tower. They are also part of a group that own the WTC lease. No where does it say that the Silverstein group is involved in Sears Tower, just two individiuals.
