The practice of U.S. corporations reorganizing overseas with foreign entities to cut taxes back home has emerged as an issue in Illinois' gubernatorial race.

Gov. Pat Quinn condemned the practice Wednesday as "unpatriotic." The Democrat says anyone running for public office supporting it is "taking advantage" of taxpayers.

The comment was directed at Republican challenger Bruce Rauner (ROW'-nur). Reports indicate Rauner says the U.S. and Illinois need to compete, not block companies. His campaign later declined to say if Rauner supports the practice.

Much attention has been focused on Deerfield-based Walgreen Co. The company is considering its option to complete a takeover of Swiss retailer Alliance Boots.

Democratic U.S. Sen. Dick Durbin urged the company not to move. His GOP counterparts blocked a bill Wednesday limiting tax breaks.
