Because of an editing error, an article in yesterday's editions of The Sun about the alliance between Sen. John Kerry and organized labor contained a misleading description of the Progressive Policy Institute, headed by Will Marshall. It is the think tank of the centrist Democratic Leadership Council, not of the AFL-CIO.
An article in yesterday's business section incorrectly identified the address of Manekin LLC's conference center in Charles Center South.
The correct address is 36 S. Charles St.
The Sun regrets the errors.
